A T-shirt tech pack turns an idea into instructions a supplier can review, sample, and produce. It does not need to be complicated, but it should answer the questions that affect fit, fabric, decoration, and finishing. A clear document also helps keep revisions organized when you compare samples or place a repeat order.
1. Style Overview and Reference
Start with the style name or code, date, revision number, target wearer, intended use, and reference images. Label front, back, and detail views. If a reference image is for mood only, say so; otherwise the supplier may mistake it for a required construction detail.
2. Fabric and Color
List fiber composition, fabric construction if known, weight, finish, and preferred color reference. Include a physical swatch or code when color matching matters. If you are open to alternatives, identify which parts are flexible and ask to review a fabric sample before approving production.
3. Measurements and Fit
Attach a measurement chart with points of measure, base size, grading direction, and any agreed tolerance. Define how chest, body length, shoulders, sleeves, and neck opening are measured. Use a diagram when a point could be interpreted in more than one way. Specify whether the target fit is regular, slim, boxy, or oversized.
4. Construction and Finishing
Note details that affect the look and durability: neckline shape, rib width, stitch type if known, hem finish, side seams, shoulder reinforcement, and any special wash or trim. Add close-up references for unusual details. If your preferred construction is not known, describe the desired result and ask the manufacturer to propose a sample.
5. Artwork, Labels and Packaging
Include print or embroidery files, dimensions, placement, thread or ink color references, label artwork, hangtag details, and packaging instructions. Identify any decoration method that must be used and any method that is only a reference. For custom T-shirts, GOWDL lists options on its custom T-shirt page; confirm the process for your selected fabric and design.
6. Quantity, Sampling and Approval
State the estimated order quantity and size breakdown, requested sample stage, delivery destination, and target date. Include a space for comments and approval status so each revision is traceable. If you are considering an existing base, compare ready-stock T-shirts and note the exact model for the supplier to quote.
Keep the tech pack consistent with the approved sample. When something changes, update the revision date and call out the changed pages or details. Do not rely on a verbal instruction to replace a measurement, color, or artwork file from an earlier version.
Frequently Asked Questions
Do I need a tech pack for a simple T-shirt?
A short specification sheet can be enough for a straightforward blank or stock style. A more detailed pack helps when you are changing fit, fabric, color, labels, or decoration.
What if I do not know a construction term?
Show a photo, sketch, or sample and describe the result you want. Ask the supplier to confirm the proposed construction in the sample before bulk production.
A useful T-shirt tech pack is specific where decisions matter and clear about what can still change. Keep it organized, update revisions, and use the approved sample as the shared production reference.
