What to Include in a Clothing Manufacturing Brief
Updated: Sep 23
A factory cannot quote, sample, or produce accurately from a rough idea. If the brief is vague, the gaps do not disappear. They turn into emails, delays, wrong trims, poor fit, and sample rounds that cost more than they should.
A good manufacturing brief gives a maker enough information to understand the product, assess whether they can make it, price it fairly, and start sampling with fewer assumptions. It does not need to be fancy, but it does need to be complete.
The best briefs are practical. They show what the garment is, who it is for, how it should fit, what it is made from, how it should be finished, and what commercial limits the factory needs to work within.
Start with the garment overview
Open the brief with a short, plain description of the product. This gives the manufacturer context before they reach the technical details.
Include:
Garment type
Target wearer
Intended season or climate
End use
Price position
Expected quality level
Any similar reference styles
For example, “Relaxed-fit women’s linen shirt for summer retail, designed as a mid-market piece with natural fibres and soft garment washing.”
That one sentence tells the factory a lot. It suggests the garment needs breathable fabric, a casual hand feel, and finishing that suits linen. It also gives the maker a sense of pricing and production expectations.
Avoid descriptions that lean too heavily on mood. Words like “premium,” “elevated,” or “effortless” can help set direction, but they are not enough on their own. Pair them with measurable details.
Better still, explain what those words mean in the context of the product.
If “premium” means French seams, shell buttons, and a heavier fabric weight, say that. If “relaxed” means 8 cm ease through the chest, add the measurement.
Define the product range clearly
If the brief covers more than one garment, separate the range into clear styles. Each style should have its own code or name.
A simple range table can help.
Style code | Garment | Key details | Colourways |
SH01 | Linen shirt | Relaxed fit, long sleeve, button front | White, oat, black |
PT01 | Drawstring pant | Wide leg, elastic waist, side pockets | Oat, black |
DR01 | Shirt dress | Knee length, self-tie belt, curved hem | White, olive |
This stops confusion when the factory quotes, samples, or asks questions. It also helps avoid crossed wires later, especially if different garments share the same fabrics or trims.
If you are still deciding which styles to produce, say so. Mark them as confirmed, optional, or in development. A supplier can then price the work properly and flag minimum order issues early.
Add drawings, photos, and reference samples
Manufacturers need visual information. A written description can be interpreted in different ways, but a drawing or reference image makes the direction much clearer.
Include front and back sketches where possible. These do not need to be fashion illustrations. Simple, flat technical drawings are usually more useful because they show seams, openings, pockets, stitching, hems, and closures.
Useful visual references include:
Flat drawings
Photos of a similar garment
A marked-up sample
Close-ups of seam finishes
Pocket and cuff references
Photos showing fit or drape
If you use reference garments from other labels, make it clear what you are referencing. You might like the collar shape from one shirt, the sleeve length from another, and the fabric handle from a third. Do not expect the factory to guess which detail matters.
Also avoid asking a supplier to copy another product exactly. Use references to explain construction, proportion, or finish, then create your own garment specifications.
Specify fabric and trims in detail
Fabric choices affect almost everything: fit, shrinkage, costing, lead time, care instructions, durability, and how the garment feels on the body.
A strong clothing manufacturing brief should name the desired fabric as clearly as possible. If the final fabric is not confirmed, give a target.
Include details such as:
Fibre content
Fabric type
Weight
Width, if known
Stretch or no stretch
Finish or wash
Colour
Print, yarn dye, or solid dye
Fabric supplier, if nominated
For example, “100% linen plain weave, around 160 gsm, garment washed, soft hand feel, opaque enough for a white shirt.”
That gives the supplier something concrete to assess. They can tell you if the fabric is suitable, if it will shrink, if it frays easily, or if it needs special handling.
Trims need the same level of care. Do not write “buttons” if the garment needs 18 mm corozo-look buttons with four holes in matte cream. Small details change the final product.
Common trims include:
Buttons
Zips
Elastic
Drawcords
Eyelets
Snaps
Labels
Hangers
Care labels
Interlinings
Shoulder pads
Thread
If trims are supplied by you, say so. If the factory needs to source them, include a target quality, colour, and material.
Include accurate measurements and fit notes
Fit is one of the biggest causes of sampling delays. A factory can make a garment to match your sketch, but without measurements, it may not match your intended shape.
At minimum, include a measurement chart for the sample size. For production, include a graded size chart or grading rules.
Key measurements may include:
Chest, bust, or waist
Hip
Body length
Shoulder width
Sleeve length
Armhole
Bicep
Hem opening
Rise, inseam, and leg opening for pants
Neck opening or collar size
The exact points of measure depend on the garment. Be precise about where each measurement is taken. A “body length” measured from high shoulder point is not the same as one measured from centre back neck.
Fit notes are just as useful as numbers. Say whether the garment should sit close to the body, skim, or feel oversized. Note where ease should sit.
For example:
The shirt should feel relaxed through the body but not oversized at the shoulder.
The waistband should stretch comfortably without twisting.
The sleeve should allow easy movement when the arm is raised.
The dress should have enough hip ease to sit cleanly when walking.
If you have a fit model or sample block, mention it. If the garment is based on an existing pattern that already fits well, provide that reference.
Explain construction and finishing
Construction details tell the factory how the garment should be made. They also affect price. A T-shirt with coverstitched hems and an internal neck bind is different from one with basic overlocking and a turned hem.
Include seam types and finishes where they matter. If you are unsure of the technical name, provide close-up photos or ask the factory for advice.
Common construction details to define include:
Seam allowance
Stitch type
Stitch density
Hem depth
Pocket construction
Collar and cuff structure
Lining or no lining
Facing details
Reinforcement points
Bar tacks
Topstitch width
Internal binding
Label placement
This is also the place to note any quality expectations. For example, stripes should match at side seams, pocket corners need reinforcement, or loose threads must be trimmed before packing.
Some products need more technical direction than others. Activewear, swimwear, tailoring, denim, uniforms, and outerwear often need detailed construction notes. A simple woven top may need less, but “simple” still needs clarity.
Set quantities, sizes, and colourways
Factories need volume information to quote correctly. Unit cost often changes depending on order quantity, colour count, fabric yield, and production complexity.
Include your estimated order quantity for each style, colour, and size. If you are unsure, provide a target range.
A simple quantity breakdown helps the manufacturer understand the scope.
Colour | XS | S | M | L | XL | Total |
White | 20 | 35 | 45 | 35 | 15 | 150 |
Oat | 15 | 30 | 40 | 30 | 10 | 125 |
Black | 15 | 30 | 40 | 30 | 10 | 125 |
This also helps with fabric planning. A factory may need to check dye lots, cutting efficiency, and minimum fabric quantities.
If you plan to reorder, say so. A supplier may approach fabric sourcing differently if the style could become ongoing rather than a one-off run.
Share target costs and commercial limits
Many brands hesitate to share their target cost, but it can save time. A factory cannot design the whole costing structure for you. If your target landed cost is firm, the supplier needs to know early.
This does not mean asking for the cheapest version of the garment. It means being honest about commercial limits.
Include:
Target unit cost
Currency
Whether the cost should include fabric and trims
Packaging requirements
Freight expectations, if known
Required margin or retail price, if useful
Sampling budget
Payment expectations
Use clear wording. For an Australian brand, that might be “Target production cost is AUD 28 per unit, excluding freight, with fabric and trims included.”
If the target cost is unrealistic, a good supplier can tell you what needs to change. That might mean reducing stitch detail, changing fabric, increasing volume, or simplifying trims.
Clarify testing, compliance, and labelling
Garments need to meet the rules of the market where they will be sold. In Australia, care labelling and fibre content need serious attention, and some product categories may need extra testing or safety checks.
Do not leave this until the end. If testing is required, it can affect fabric choice, lead times, and budget.
Include requirements for:
Fibre content labelling
Care instructions
Country of origin information
Size labelling
Brand labels and swing tags
Barcode stickers, if required
Colourfastness testing
Shrinkage testing
Pilling testing
Flammability or safety testing for relevant products
Children’s clothing, sleepwear, workwear, and performance garments may have extra requirements. If a retailer has its own compliance manual, include it with the brief or summarise the relevant points.
Packaging should also be defined. State whether each garment needs a polybag, tissue, hanger, folded pack, carton labelling, or plastic-free packaging.
Give a realistic timeline
A brief should show when you need each stage completed. Timelines help the manufacturer decide whether the work is possible before they commit.
Include dates or target windows for:
Brief submission
Quote deadline
First sample
Fit comments
Revised sample
Sales sample, if needed
Fabric approval
Bulk production start
Final inspection
Delivery deadline
Be realistic. Sampling, fabric sourcing, lab dips, testing, production, packing, and freight all take time. If a deadline is fixed, explain why. For example, a wholesale showing, retail launch, or seasonal delivery window.
Rushed briefs often create rushed production. If timing is tight, the supplier may suggest a simpler construction method, available fabric, or smaller first run.
Make responsibilities clear
A good brief explains who is responsible for what. This avoids assumptions that can cause delays or extra costs.
Clarify who will provide:
Patterns
Grading
Marker making
Fabric
Trims
Labels
Packaging
Tech pack
Fit model
Testing
Freight booking
Final quality approval
If the factory is supplying everything, state that. If you are sending nominated materials, include delivery dates and supplier details.
You should also name the approval process. Say who signs off samples, lab dips, trims, labels, and bulk production. If no production should start without written approval, make that clear.
Attach the right supporting files
The brief itself should be easy to read, but it does not need to hold every technical detail in one document. Attach supporting files where needed.
Useful attachments include:
Tech pack
Measurement chart
Graded size chart
Pattern files
Print artwork
Embroidery artwork
Label artwork
Colour standards
Fabric swatches
Trim cards
Reference photos
Compliance documents
Packaging instructions
Use clear file names. “SH01 linen shirt tech pack version 2” is much easier to manage than “finalfinalnew.pdf”.
Version control matters. If you revise a measurement, trim, or construction note, update the file name and date. Make sure the factory knows which version is current.
Common mistakes to avoid
Most manufacturing issues come from missing information rather than bad intent. The brief leaves a gap, and someone fills it with a guess.
Common mistakes include:
Sending only mood images
Forgetting back views or internal details
Giving no target quantity
Leaving fabric choice too open
Using vague fit language
Not showing how measurements are taken
Forgetting trims and labels
Giving no target cost
Changing details after sampling without tracking versions
Assuming the factory knows local compliance needs
The easiest way to check your brief is to imagine handing it to someone who has never seen the garment before. Could they quote it? Could they make a first sample? Could they ask precise questions instead of basic ones?
If not, add more detail.
A simple checklist for your next brief
Before sending a brief to a manufacturer, check that it includes the core information below.
Product details
Garment type, target wearer, use, season, quality level, and style codes.
Visual references
Front and back sketches, reference photos, close-ups, and marked-up samples where useful.
Materials
Fabric content, weight, construction, colour, finish, trims, labels, and nominated suppliers.
Fit and measurements
Sample size chart, points of measure, fit notes, grading details, and fit model information if available.
Construction
Seam finishes, stitching, hems, pockets, linings, reinforcements, and quality expectations.
Commercial details
Quantity, size split, colourways, target cost, packaging, timeline, and approval steps.
Compliance
Care labels, fibre content, testing needs, safety requirements, and delivery market rules.
A clear manufacturing brief does more than organise information. It shows the factory that the product has been thought through. That leads to better questions, sharper quotes, smoother sampling, and a stronger finished garment.
Start with the details you know, mark the parts still being decided, and keep every revision tidy. The more clearly the brief speaks, the less the factory has to guess.
