WHAT WE BUILD
From halter cuts to high waisted silhouettes, our custom plus size swimsuit manufacturing team brings every style to life - brief to finished product.

Long sleeve
Full-coverage arms with UPF-friendly construction for sun protection and a sleek, modern silhouette.

Halter
Ties at the neckline for adjustable support, creating a flattering open-shoulder look.

High waisted
A retro-inspired bottom with an elevated waistline that smooths and sculpts the midsection.

One piece
A single custom-cut garment offering full-torso coverage with streamlined, supportive design.

Racerback
A Y-shaped back panel that frees the shoulders and provides enhanced range of motion.

Your spec
Bring your own pattern or tech pack and we build to it.
A clean plus size swimsuit in Nylon with no branding is straightforward factory work. A fully custom one piece built with sublimation - all-over dye prints locked permanently into the fabric across every panel and seam - is the kind of construction our production team handles daily. The elaborate end is the norm for the brands we work with, not the exception.


START YOUR BRIEF
You don't need a finished design to begin. Bring a sketch, a reference plus size swimsuit, a tech pack, or an AI-generated spec, and we develop it into a production-ready plus size swimsuit.

A rough concept is enough to start a plus size swimsuit brief.

Send a spec or a reference plus size swimsuit and we build to it.

Bring a spec from ChatGPT, Gemini, or Copilot. We productionize it.
