Extended-Cup Bra Development: What to Verify Before Bulk

List each required band-and-cup combination and identify the sizing convention used by your brand. Provide the actual body-measurement guidance and garment measuring points. Do not infer cup equivalence from letters shared by different charts.

Describe the intended support, shape, neckline and adjustment range. Use measurements and an identified reference sample to explain problems such as gaping, pressure or insufficient coverage, rather than asking for an unspecified bigger cup.

Ask which requested combinations have a current pattern, physical sample and documented fit review. A printed chart is not proof that all its sizes have been made or approved. Record unavailable or untested combinations explicitly instead of allowing the largest claimed size to imply a complete range.

Document cup panels or moulding, wire if present, cradle, wings, band, straps and closure. Their combined behaviour matters more than one visible feature. A wider strap or additional hook is not, by itself, proof of support.

Use consenting adult fit participants and the agreed activities and duration. Record fit changes, pressure, movement and adjustment limits across the planned range. Repeat relevant measurements and checks after the agreed care procedure; do not turn one successful sample into a whole-range performance statement.

Freeze the approved specification, sample version and validated combinations before bulk. Define what a material, wire, cup or grading change will trigger: a new review, new samples or additional testing. Keep unvalidated sizes out of a claim that the whole range is ready.

For LXSC, original-design custom production starts from 10,000 pieces, subject to feasibility and confirmed allocation. An enquiry is a request to assess capability, not a guarantee that the requested extended-cup design can be supplied.
