Crinkle swimwear that fits and stays put

Flawless Stretch™ is our crinkle swimwear, made from Italian Carvico fabric: 92% polyamide and 8% elastane, Oeko-Tex certified. The textured crinkle knit has 4-way stretch with high recovery. It moulds to your shape and bounces back after every wear, so it doesn't sag when it's wet.

Because the fabric stretches so much, styles come in just two fit bands, XS–L and XL–3XL. Every piece is fully lined, stays opaque wet or dry, and dries in minutes. Shop matching crinkle bikini sets, or see our tan-through swimwear for a tan with no strap lines.

Crinkle swimwear FAQ

What is crinkle swimwear?

Crinkle swimwear is made from a textured, puckered knit that gives it its signature look. Ours is woven with 4-way stretch and high recovery, so it hugs your shape and holds it.

How does the sizing work?

The fabric stretches across a wide range, so most styles come in two fit bands: XS–L and XL–3XL. Check the size chart on each product page to pick your band.

Is crinkle swimwear see-through when wet?

No. Flawless Stretch™ pieces are fully lined and stay opaque wet or dry.

How do I care for crinkle swimwear?

Rinse in cold water after swimming and dry in the shade. Don't use a dryer, bleach or fabric softener, and avoid long chlorine soaks.
