One-Piece Swimsuit Customization Program for E-commerce Private Label with Ultrasonic Welding
One-Piece Swimsuit Customization Program for E-commerce Private Label
This programme covers the full path from a one-piece swimsuit concept to repeatable bulk supply for e-commerce private label. The build starts from everyday-casual references — one-piece swimsuit in modal blend — then locks fabric weight, wash behaviour and fit tolerance so every reorder matches the approved sample.
Most one-piece swimsuit buyers arrive with one of these problems: the fabric felt thinner than the approved sample, or colour faded after a few washes. The fix is a written spec before bulk: shrinkage allowance, stitch density, colour tolerance and a golden sample kept at the factory.

FAQ
How long does sampling take?
A first prototype is typically ready in 7 working days after the tech pack is confirmed, including fabric sourcing if the base cloth is not in our stock library. Revisions add about 4 days each.
Can you match a specific colour?
Yes. Send us a Pantone TCX reference or a physical swatch. We return lab dips for approval and hold bulk shade within the agreed tolerance band before cutting.
How is shipping handled?
We quote EXW, FOB, CIF and DDP. Consolidated sea freight is the default for bulk programmes, with air or express options when a launch date is at risk.
What file formats do you need for artwork?
Vector files (AI, EPS, PDF) give the best print and embroidery results. For raster artwork please supply at least 300 dpi at the final print size. We digitise embroidery files in-house and return a sew-out photo for approval.
