See-Through Panelling Solutions for Sports Bras: Sample to Bulk Timeline
A realistic plan for developing technical sports bras with see-through panelling solved, from first sample to repeat bulk.
Stage one: definition
Fix opacity above 95% for every panel and the construction route. This is where most delays originate, because unclear targets cause repeat sampling. Because the underband and strap anchors carry repeated load, target checks are made on a worn sample rather than flat fabric alone.
Stage two: laboratory sample
Request lab dips and a first fabric sample. Confirm against AATCC 183 with panel-level measurement before cutting, then cut 3-5 pieces for fit. Keep AATCC 183 with panel-level measurement named in the tech pack so every lot is measured the same way.
Stage three: wear trial
light or printed panels become transparent under stretch appears during use. Run a two-week trial with everything from yoga to high impact training participants before approving bulk. Where technical sports bras is worn for everything from yoga to high impact training, set tolerances around that range of movement.
Stage four: pre-production
Produce 30-50 pieces from bulk materials. This exposes process variation that a hand-made sample hides. Any change to power mesh and bonded spacer panels requires re-testing against opacity above 95% for every panel before bulk is released.
Stage five: repeat orders
Once approved, keep the recipe and report set together so the next order can be released without redevelopment. Past reports from AATCC 183 with panel-level measurement help the mill reproduce the same recipe on the next order.
