About

Our pieces are consciously designed to accentuate the body you've learnt to love. Made locally in Quebec using recycled fabrics, we feature timeless swimwear that you'll never want to take off. In a world full of fast fashion we chose to slow down. 

We believe in choosing well, buying less, and making it last because sustainability never goes out of style. 

This is the new Thirties.

Made locally

All of our swims are ethically made here, in Quebec. We are seeking to offer the best quality at the best retail price.
