A useful tech pack does more than list garment details. It tells a factory which decisions are final, which choices are still open and what a sample needs to validate. The goal is not to make a perfect document before you speak with a supplier. It is to reduce avoidable interpretation so the supplier can review construction, fit, materials and timing against the same working brief.
1. Separate fixed decisions from open questions
Start with the details that define the product: the intended silhouette, base size, key construction features, reference images and non-negotiable visual elements. If a trim, fabric or finish is still under review, label it as a question rather than presenting it as a final instruction.
This distinction gives the factory a clear path for feedback. It can assess what is specified, identify gaps and suggest what needs confirmation before sample work begins. A document that exposes its open questions is often more useful than one that hides uncertainty behind general wording.
- What the sample must validate
- What cannot change from the design direction
- Which material, trim or finish decisions are open
- Who owns final approval on the brand side
2. Review the pack from the factory's point of view
Before sending the brief, check whether a reader can connect each sketch, measurement, material callout and construction note. A front view without a matching back view, a measurement chart without a base size or a trim note without a placement reference can create clarification work before a supplier can scope the sample.
Use one current version number and one consolidated feedback file. This is especially helpful when design, merchandising and sourcing teams all contribute to the brief. It makes the latest instruction visible and reduces the risk of different pages describing different versions of the style.
- Front and back technical views
- Base size and measurement direction
- Construction, trim and decoration placement
- Version number, date and review owner
3. Use the sample review to close the right decisions
DONGFAN's sample-development window is usually 2–3 weeks, depending on the number of styles and development complexity. The sample should be reviewed against the purpose stated in the brief: visual direction, fit, material behaviour, construction or a later production reference. It should not be judged against undefined requirements.
After review, send one dated list of changes that distinguishes must-change items from preferences. That gives the next discussion a defined scope and makes it easier to confirm whether another sample, a material review or a production-ready specification is needed.
- State the sample purpose
- Consolidate fit, construction and material comments
- Separate required changes from optional ideas
- Confirm next-step scope with sales
FAQs
Do I need a finished tech pack before requesting a sample?
No. A reference image, sketch or existing sample can start a discussion, but clearer specifications help the factory review the scope.
What should a sample brief make clear?
It should clarify the garment direction, measurements or fit reference, materials, trims, quantity, target timing and the purpose of the sample.
How do I avoid conflicting comments?
Use one current file version and consolidate feedback into one dated change list before sending it to the supplier.
