Luxury Swimwear

The mission of our co-founders Heidi Gosman and Penny Klein, was to create luxury bikinis and swimsuits that help women celebrate their bodies, feeling confident and relaxed no matter what destination they have ventured to.

Our luxury swimwear works behind the scenes, thanks to hidden support features, to both flatter and support all shapes and sizes, while our timeless styles are able to be worn for years to come.
