FAQ

Lingerie/swim questions

Can you spec underwire?+

Yes — wire type (e.g., nylon-coated steel), wire size by cup, channel casing material and width, and stitch type for channel.

Cup spec — what level of detail?+

Cup dimensions to the mm, cross-cup spec, underband depth, foam thickness, cup grading per band size.

Chlorine-resistant fabrics — do you source them?+

We can suggest vetted suppliers (Carvico, Eurojersey) and spec fiber blend (e.g., 80% poly / 20% Lycra Xtra Life).

Lined vs unlined construction?+

Yes. Lined panels for opacity, unlined for soft hand. We spec which fabric, where, and how it's attached.

Bonded vs sewn seams?+

Bonded for clean inside finish (no chafe). Sewn (flat-lock) for structural seams. We spec which seam type per location.

Elastic types & widths?+

Picot elastic (decorative edge), fold-over elastic (FOE), plush-back elastic, channel elastic. We spec width, grade, and supplier.

What's a gusset for swim?+

Gusset = lined panel in crotch zone. For swim, typically 100% poly or mesh, attached with bonded seams.

Sample fit iterations — typical count?+

2–3 iterations is standard for lingerie/swim. We bake this into our Custom tier (4 revisions included).
