Pattern grading for activewear

Grades must respect stretch zones, gussets, bra band growth and dress lining lengths. Put graded measurement charts in the tech pack — tech pack requirements.

Support and fit development notes

Sports bra support level development needs cup map + fabric recovery + strap geometry. Guide: sports bra support construction. Tennis built-in shorts: built-in shorts construction.

Do not bulk without PPS

Use PPS approval checklist. Written sign-off beats chat approvals.

FAQ

What is the difference between proto, fit sample and PPS?

Proto proves make; fit sample validates size/fit; PPS locks production-intent before bulk.

Why is activewear grading special?

Stretch, compression and support change how grades behave across the size run.

Can I skip fit on library styles?

You can start faster, but still confirm size chart and key measurements on the colourway you will buy.

When should sports bra support be re-tested?

When cup map, elastics or fabric hand changes — see support development guide.
