Shirt Manufacturer Guide: How Shirts Are Manufactured for Brands and Uniforms
A woven shirt is one of the most component-heavy garments a brand can make. Collar, collar stand, cuffs, placket, yoke, pockets and buttonholes all have to be cut, fused and sewn precisely, and small errors show immediately at the neck and front. Choosing a shirt manufacturer and briefing them well comes down to specifying those components clearly and approving them on samples.
This guide explains how shirts are manufactured, which fabrics and construction details to specify for fashion, work and uniform shirts, and what to send your manufacturer for an accurate quotation.
Types of shirts and what each needs
| Shirt type | Typical fabric | Key details |
|---|---|---|
| Dress and formal shirts | Fine cotton poplin, twill, oxford | Crisp collar and cuffs, fine stitching, pattern matching |
| Casual shirts | Oxford, chambray, flannel, linen blends | Button-down or camp collars, softer interlining, washed finishes |
| Work and corporate uniform shirts | Poly-cotton poplin or twill | Easy care, durable seams, embroidery positions, consistent colour across reorders |
| Tactical and field shirts | Ripstop or twill blends | Flap pockets, pen slots, sleeve pockets, reinforced stress points |
| Ceremonial and specialist shirts | Cotton, cotton-rich blends | Wing collars, ghillie lacing, specific fastenings |
ZESTLET examples include the tactical combat shirt, the shirt in our BDU set, the wing collar shirt and the ghillie shirt.
Specify the fabric
Woven shirt fabrics are described by fibre, weave, yarn and weight. Poplin is smooth and crisp, oxford has a textured basket weave, twill shows a diagonal line and resists creasing, and ripstop has a reinforcing grid for durability. Cotton gives comfort and breathability; blending with polyester improves wrinkle resistance and colour retention for frequently laundered uniforms.
Ask for shrinkage and colourfastness results on the actual fabric. For checks and stripes, decide whether pockets, yokes and plackets must match the pattern, because pattern matching uses more fabric and more cutting time. See our fabric sourcing guide for the approval sequence.
Components to define in the tech pack
| Component | Options to specify |
|---|---|
| Collar | Spread, point, button-down, band (mandarin), camp or wing; point length; stand height |
| Interlining | Fused or sewn; weight and firmness for collar, stand, cuffs and placket |
| Cuffs | Barrel (one or two buttons), convertible or French; sleeve placket style |
| Front placket | Plain front, top-stitched placket or hidden button placket |
| Yoke and back | Single or split yoke; box pleat, side pleats, darts or plain back |
| Pockets | Patch, flap, pleated or with pen slot; position measured from high point shoulder |
| Hem | Curved shirt-tail or straight hem; side gussets |
| Buttons | Material, size, number of holes, colour and spare buttons |
| Uniform details | Epaulettes, badge tabs, name tape and embroidery positions |
Stitch density matters: finer, denser stitching looks more refined on dress shirts, while workwear needs strong seams and reinforced stress points. State stitches per inch and seam type in the tech pack so samples and bulk match.
How shirts are manufactured
- Fabric inspection and relaxation: rolls are checked for defects, shade and shrinkage before cutting.
- Spreading and cutting: fabric is laid in layers and cut to the graded pattern; striped and checked fabrics are aligned for matching.
- Fusing: interlining is bonded to collar, stand, cuffs and placket with controlled heat and pressure.
- Part preparation: collars and cuffs are sewn, turned, pressed and top-stitched; pockets and plackets are prepared.
- Assembly: yoke, shoulders, sleeves and side seams are joined, then the collar and cuffs are attached.
- Buttonholes and buttons: buttonholes are sewn and cut, and buttons attached in matching positions.
- Hemming, trimming and pressing: threads are trimmed and the shirt is pressed and folded with collar support if required.
- Inspection and packing: measurements, symmetry, stitching and labels are checked against the approved sample. See quality control and inspection.
Fit and sizing
Decide the fit (slim, regular or classic) and size system. Retail dress shirts are often sized by collar and sleeve length, while casual and uniform shirts usually use S–XXL or numbered sizes. The size chart should give garment measurements for collar, chest, waist, hem, back length, shoulder, sleeve length and cuff circumference, with tolerances. Approve the base size on a person, then grade. Our pattern making and grading guide explains the process.
What drives the price of a shirt
- Fabric quality, weight and pattern matching
- Number of components: pockets, flaps, epaulettes and pleats
- Interlining quality and collar construction
- Buttons and trims
- Embroidery, badges and name tapes for uniforms
- Packing method, such as folded with collar support or hung
- Quantity per style and colour; see clothing MOQ explained
Common shirt manufacturing mistakes
- Collar points that do not match. Specify point length and approve the collar on the sample.
- Bubbling interlining. Test fusing after washing before bulk.
- Mismatched stripes or checks. State matching requirements clearly.
- Embroidery positions given in words. Give measurements from fixed points for every size.
- Ignoring reorder colour. Uniform shirts must match earlier batches; keep approved shade standards.
Frequently asked questions
What fabric is best for uniform shirts?
Poly-cotton poplin or twill is a common choice because it balances comfort with easy care and colour retention. Pure cotton feels more breathable but creases more.
Can a shirt manufacturer match my existing sample?
Yes. Send the sample with your size chart and any changes. The manufacturer can make a counter sample for approval before production.
What is a split yoke?
A split yoke is cut in two pieces with a seam at the centre back. It allows a better fit across the shoulders and is a sign of careful construction on dress shirts.
Can you add embroidery and badges to shirts?
Yes. Logos, badges, name tapes and rank tabs can be added. See custom embroidery and patches.
Does ZESTLET manufacture private label shirts?
Yes. ZESTLET makes custom and private label shirts, including uniform, tactical and Highland shirts, with samples approved before bulk production.
