WHAT WE BUILD

Custom plus size swimsuits we build

Your spec

From nylon plus size swimsuits to your most elaborate vision

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.
