7 Common Fashion Tech Pack Mistakes to Avoid

Understanding Tech Packs

A good tech pack is precise, clear, and contains everything a factory needs to produce your garment accurately. Below, I’ll discuss seven common fashion tech pack mistakes I often see and explain why they can be detrimental to your production process.

Many founders either leave out crucial details or include unnecessary information. Here are seven things worth removing from your tech pack before it goes anywhere near a manufacturer.

1. Overly Obvious Construction Notes

Notes like "stitch lines must be straight" or "no skipped stitches" are assumed by any competent factory. Including them signals a lack of trust in your manufacturer and can damage the working relationship before it starts. Stick to specifying things that are actually open to interpretation. The basics are already understood.

2. Fashion Sketches

A tech pack needs technical flat sketches—precise, clean, industry-standard drawings that show every seam, stitch line, and construction detail from front to back. Fashion illustration sketches are beautiful, but factories can't work from them. If your tech pack contains anything that looks like it belongs in a lookbook, replace it with a proper technical flat.

3. Your Brand Story or Inspiration

A tech pack is a production document, not a brand deck. Your manufacturer doesn't need to know the story behind the collection, your target customer, or your brand values. Save all of that for your lookbook, website, and investor pitch. It has no place in a tech pack and adds unnecessary pages that dilute the technical content.

4. Tolerance Tables That Are Too Granular

Specifying tolerances of ±1mm sounds precise and professional, but it's unrealistic for garment production. This can create unnecessary conflict with your factory when samples come back. Standard garment tolerances are typically ±3–6mm depending on the measurement point. Setting tolerances too tight doesn't improve quality; it just creates friction.

5. Retail Pricing or Cost Targets

Including your target retail price or cost of goods in a tech pack is a mistake. It hands your manufacturer information they can use to anchor their production quote—not in your favor. Pricing conversations belong in a separate negotiation, not embedded in your technical documents.

6. Full Graded Specs Before Fit Is Finalized

Grading your specs across a full size range before you have a finalized fit sample is premature. Get your base size right first. If your base size specs are off and you've already graded the full range, you've multiplied the problem across every size. Wait until fit is confirmed before committing to a full grade.

7. Terms and Conditions Pages

Legal language belongs in your manufacturing contract—not your tech pack. A tech pack is a technical document. Adding terms and conditions muddies its purpose and doesn't provide the legal protection you're looking for anyway. If you need a manufacturing agreement in place, handle that separately before production begins.

The Bottom Line

A tech pack that's cluttered with unnecessary content is harder to work with than one that's incomplete. Manufacturers work from what's in the document—the cleaner and more focused it is, the better your samples will be.

If you're not sure whether your tech pack is hitting the right balance, that's exactly what a review or a discovery call is for.
