What changes when you own the pattern
Patterns, grade rules, specifications and sealed samples are what make a garment portable between makers, and who owns them should be settled in writing before development starts.
On this page 7 sections

A founder needs both the right to use the product's development work and access to the current patterns, graded specifications and approved samples. Possession of files, intellectual-property ownership and permission to transfer work to another maker are separate questions. The agreement should settle all three before the brand depends on the work.
A garment is not really an object in a warehouse. It is a set of instructions that can be repeated, and whoever holds those instructions holds the ability to repeat them. When they exist only inside a maker’s office, the arrangement with that maker is not a supply relationship. It is the product.
01The base pattern, the grade, the specification and the sample
The first of those instructions is the base pattern: the flat pieces that produce the intended shape in one size, drafted for a particular cloth and a particular way of making. It carries seam allowances, notches, grain lines and the sequence in which the pieces meet. Two makers given the same sketch will draft two different patterns and sew two different garments. Given the same pattern, they are working from one instruction.
Without it, what a brand holds is a finished garment and pictures of it. A garment can of course be copied, taken apart or measured and redrawn, but what comes back is not the same instruction. Whoever copies it has to infer seam allowances from a sewn seam, guess how much the cloth moved in pressing and washing, and reconcile the result against their own house block, which is the shape their machines and their operators already make well. The copy usually measures correctly and hangs differently, and the difference appears where the body is: the armhole, the shoulder slope, the way a sleeve sits at rest.
The grade rules extend the approved base size across the size set, and they are a set of decisions, not a proportional enlargement. How much goes to the chest, how much to the shoulder, where length is added, which points hold still. A grade that is written down is a rule another person can apply. A grade carried as habit by whoever did it the first time cannot be recovered once that person is out of reach.
Regrading from produced garments turns a small loss into a range problem. Every garment measured carries tolerance, so the rule inferred from a set of them is the original rule plus whatever that particular run happened to do. The steps between sizes shift, usually in the middle of the range where most of the volume sits. Nothing looks wrong on any single garment. What a founder sees is that customers who reordered their usual size sent it back, and that the sizes coming back are not the sizes that used to.
The technical specification says what the garment is made of and how it is put together: cloth weight and composition, trims, stitch types, seam finishes, thread, label placement, packing. It also carries the points of measure and the tolerances allowed at each one. It is the reference a quality check is made against, and the answer to any argument about whether a delivered garment is correct.
It is also what makes a substitution decidable. A trim goes out of production, a thread shade is unavailable, an interlining changes. With a specification, the maker proposes a replacement against a written requirement and someone approves it. Without one, the substitution is made quietly by the person holding up the line, and the first anyone hears of it is a garment that behaves differently after a wash. A quality argument conducted without a specification is a negotiation about what two people remember agreeing.
Then the approved sample and the measurement record. The sealed sample is the physical standard, the garment everyone agreed was right, dated and stored. Its value is in being physical, because it settles questions of hand feel, drape and finish that a written specification can describe but not prove. The measurements taken from it protect against drift, where each run moves a little and no run ever looks wrong beside the one before it.
A sealed sample only works if it is genuinely sealed: agreed, signed, dated and held as a pair, so both sides can point at the same garment. It has to be reissued when a correction is approved, because a standard a season out of date is worse than none. The brand’s copy has to sit somewhere a person other than the founder can find it. The measurement record is what makes the standard checkable at a distance, which matters because most production is approved from measurements and photographs rather than by someone standing in the room.
02A wash cannot be reproduced from a photograph
Where a garment is finished after it is sewn, the finish is a process and not a description. A garment dye, an enzyme or stone wash, an over-dye, a softener, a pressed finish, a print laid in a particular position: each is the output of a recipe run on particular machinery at a particular load. Colour, hand and the way the cloth will age are all decided there, and none of them can be read back off the finished garment closely enough to repeat.
So a finish needs two things recorded, and one of them has to be physical. The recipe, in the terms the laundry actually works in, and a sealed standard, a swatch or a garment kept as the reference, with a stated tolerance for how far a run may sit from it. A brand holding only an approved photograph holds an image of a colour under one light.
The absence of a finish standard shows up as a range that stops matching itself. A repeat of the piece that sold best comes back fractionally off the first run, and beside the original on a rail it reads as a fault rather than as a variation. It is also the artefact most often left behind when production moves, because the founder is thinking about patterns and the wash lives with a different supplier again.
The digital files are the same argument in another medium. The graded pattern as a working file rather than a flattened print or a picture of one. The marker, where one was made. Print artwork at full size with the colours separated, not a compressed export. The embroidery file, which is a stitch instruction and not an image. Care and content label artwork. The specification itself in a form somebody can edit.
A printed pattern is a record; a file is a tool. The difference is that a file can be graded, corrected, sent and reissued, where a print can only be traced. Ask for what is current, in a form that opens in something other than one supplier’s own system, and ask again after each round of corrections, because the copy worth holding is the last one rather than the first.
03What a second maker needs before a quote means anything
Together these make a garment portable. A second maker can quote on the same product and the quote will be comparable, because both parties are pricing the same instructions. Without them, the second maker is quoting on a re-development, and a difference in price may turn out to be a difference in what is being made. Competitive quoting is not genuinely available to a brand that cannot describe its own garment precisely.
Set out plainly, a maker taking on an existing garment needs the cloth specified and a physical reference of it, the pattern either graded or in a size they can grade from, the specification with its points of measure and tolerances, a sealed sample, and the finish standard where there is one. Whatever is missing from that list, the maker fills in from their own practice. That is not sharp dealing. It is what a competent factory does when an instruction is absent, and it is the only thing it can do.
This is why a garment that lives inside one factory’s tooling is not portable however good the relationship is. Tooling here is not only machinery. It is the house block the pattern was derived from, the fusing used, the allowance made for shrinkage in that cloth because they have run it before, the way the marker is laid, the settings the machines are left on, the operators who have made this style often enough to have stopped thinking about it. None of that is written down anywhere, because it never needed to be. Nobody is withholding it. There is nothing to hand over.
Good will transfers none of it. A maker who behaves entirely straight will send everything they hold and the garment will still change, because what they hold is not what made the garment. A strong relationship makes this invisible rather than untrue, which is why the question is usually asked for the first time by a founder who has never had a bad experience with a supplier.
04What a founder can do the week a supplier stops
Portability matters because supplier relationships end for ordinary reasons. Capacity is committed to a larger customer. A factory changes hands. Quality drifts and the conversations stop working. A shorter lead time is needed, or a specialist for one product, or production closer to the customer. None of that is a disaster until leaving means starting the garment again.
Take the first of those. A founder has a first range in production and a second season being planned. The maker says, without any drama, that capacity for the coming season has gone to a larger customer. The range is selling, the photography is shot, the size chart is published, and two styles are due to be reordered.
Holding the documents, the founder sends the same package to two or three other makers: pattern, graded nest, specification, sealed sample, finish standard. The quotes come back comparable, because every one of them is pricing the same garment. The chosen maker sews a pre-production sample, it is measured against the record and checked against the sealed garment, one or two things are corrected because every factory is slightly different, and those corrections are written back into the pattern. The cost is a sampling round and some weeks in the calendar. The garment on the website is still the garment in the box.
Holding only a garment, the founder sends the garment. Each maker quotes on developing it, so the quotes are not comparable: the cheapest is cheap because it intends to use its own block, and nothing in the number says so. The first fit comes back close. The second is closer. Somewhere around the third the founder accepts a garment that is right in its own terms and is not the garment customers bought, and the published size chart now describes something else.
The compounding happens in the photography and the copy. A range is sold on images of one specific garment, and when the garment changes the images become a promise the product no longer keeps. Reshooting is a cost nobody budgeted for. Not reshooting is a returns problem, and it reaches the founder as a sizing complaint rather than as the sourcing decision it actually is. The people who notice first are repeat customers, and they notice by returning the size they have always worn.
The moment a founder finds out what they actually hold tends to be the moment they want to move, which is the worst available time to ask for it. The request arrives when the other side can read exactly why it is being made.
05The second range inherits a fit, or pays for it twice
Ownership also decides whether a first range becomes an asset or a cost that repeats. A documented block that has been fitted, corrected and proved is the starting point for the next garment built on it, so the second range inherits a fit that is already right and spends its development on what is new. A brand without those documents pays for the same learning twice, and often gets a slightly different garment for the money.
What accumulates in a pattern is corrections. A shoulder taken in because it stood away from the body. A sleeve head reduced because it puckered in that cloth. A front shortened because the neckline gaped when the wearer moved. Each of those was found by putting a garment on a person and looking at it, and each is now held in the shape of the pieces. Built onto, the next style starts from a fit that has already been earned and spends its development on whatever is genuinely new about it.
Across a range, that is what a customer experiences as a brand that fits them. Styles built off one block relate to each other, so a size that worked once works again and the next thing can be bought without being tried on, which is the condition for selling clothing at a distance at all. A brand that develops every style from nothing has a size chart that is accurate style by style and inconsistent across the range, and a customer reads that inconsistency as the brand being unreliable rather than as two patterns having different origins.
The same asset decides how cheaply a range can be extended. A second colourway, a longer length, a different sleeve or the same shape in a heavier cloth is a small piece of work with a predictable outcome when it starts from a documented block. Attempted without one, each of those is a development in its own right, which is why a second season can cost what the first one did and produce less.
06Some development genuinely belongs to the maker
There is a real boundary here, and the argument is weaker for pretending there is not. Some of what a maker brings is theirs in a way that paying for one brand’s sampling does not touch. A block developed over years for the body they specialise in and used across many customers. A wash they worked out and sell as a house finish. A construction they devised, a machine they bought, a cloth they had developed with a mill and hold exclusively. Asking to take those away is asking for the maker’s business rather than for the brand’s product, and a founder who does it will deserve the answer they get.
Three questions help define the negotiation: did the asset exist before this project, is it offered to other customers, and what was developed specifically for this garment? Those questions do not establish ownership by themselves. Record the agreed rights in new work, any licence to underlying house blocks or processes, and permission to use the resulting files with another maker. The contract and applicable law determine the result.
Where a finish or a construction really is proprietary, the useful move is not to argue about it. It is to know, and to say so internally: this style is not portable, and reproducing it elsewhere means developing something close rather than the same. That converts a hidden dependency into a priced one. A founder can decide a signature piece is worth being tied for, and can decide a range should not contain three of them. The damage is never the dependency. It is finding out about the dependency in the week it matters.
Plain styles deserve the same care as signature pieces. They may be the products that support the business, and apparent simplicity can hide proprietary blocks or finishes. Confirm both the rights and the current documents before treating a style as portable; do not let an apparently easy garment bypass that conversation.
07Asking at quotation stage is a commercial question, not a signal of distrust
The strongest objection to all of this is about timing. A new brand asking a maker to settle rights before a first order has been placed looks like distrust arriving ahead of the work, at the point where the founder has least to offer and most to lose. Makers with good capacity choose their customers, and a small order that turns up with paperwork attached is an easy one to schedule behind a larger one that turns up without any.
The objection describes a real risk and puts it in the wrong place. What makes the request read as distrust is when it is made, not that it is made. At quotation stage nothing has been spent and nobody has committed, and the question is indistinguishable from every other question about the deliverable: what the price includes, what the lead time is, what arrives at the end. Any maker who works with brands rather than only with wholesalers has answered it many times, and the ones who work with buying offices carry the answer on their own paperwork already.
The same sentence, asked well into a relationship, is a different sentence, because by then there is only one reason anyone asks it. That is the version that damages the relationship, and it is the version a founder is forced into by not having asked at the start.
The answer is worth having either way. A maker who says plainly that patterns drafted for a customer belong to that customer has told you they work with brands. A maker who cannot answer, or who has never thought about it, has told you something just as useful before either side has spent anything. The question is cheap and the information it returns is not available any other way.
Paying for development does not by itself establish every right in the result. For example, the UK Intellectual Property Office's guidance on commissioned copyright works explains the importance of a written agreement. The relevant rights and defaults depend on the asset and jurisdiction. Have the agreement cover ownership, licences, editable-file delivery and transfer to another supplier explicitly.
So settle it in writing before development starts. Establish who owns the pattern, the grade, the specification, the sealed samples, the photographs and the source files for anything digital. Establish the form they arrive in, editable and current instead of a flattened print. Establish what happens to all of it if the relationship ends, and how quickly. Asked at quotation stage this is an ordinary commercial question, and a maker who works with brands regularly will answer it without difficulty.
Keep the signed agreement accessible to the people placing orders. Reference the relevant rights and deliverables in quotations and order confirmations, and state how those documents relate to the agreement. A convenient summary helps the team; it does not replace the legal terms or decide which document takes precedence.
Holding the documents is worth only what the documents say. A pattern that stopped matching the garment three rounds of corrections ago is a record of an earlier product. Keep a copy on the brand’s side, dated, reissued every time a correction is approved, with the sealed sample somewhere a person can find it.
Keep the superseded versions rather than overwriting them, so a question about last season’s garment can still be answered, and name the person who does the reissuing. A task that belongs to everybody is done by nobody, and this particular failure is silent until the season a new maker is sent a file describing a garment that was corrected twice after it was saved.
Our own position on this is stated plainly. The agreed client deliverables are handed over with their source files and account access. The scope should identify any third-party fonts, software, stock assets or proprietary supplier processes and the licences or limits that come with them.
A brand name protects what a company is called. These documents protect what it sells.
