Founded in the heart of Quebec in 2020, The Thirties creates swimwear for women designed for absolute comfort.

Our bikinis and swimsuits stand out through their exceptional technical construction: fully lined, designed with minimal seams to eliminate pressure points. Several models feature adjustable ties with 3 size options for a personalized fit. Available from XS to XL, every detail is designed so you feel perfectly comfortable, whether poolside, at the beach, or during a relaxing spa moment.

A premium approach that makes all the difference. Our creations combine artisanal craftsmanship and impeccable finishes to offer you pieces that last and enhance your beauty, season after season. Made in Canada with top-quality materials. Several of our models incorporate recycled Italian fabrics, combining lasting performance with environmental responsibility. Our creations are designed and crafted locally by specialists who master the art of custom swimwear.

Because in the end, it’s not just about the swimsuit, but about how you feel in it.

Launched in spring 2025, the Seaside Escape collection is inspired by the serenity of coastal getaways. Designed and made in Canada, these swimsuits combine comfort, quality and timeless elegance. The earthy palette includes deep brown, classic black, soft sky blue and a warm floral print that reflect calm and simplicity. Created for women who travel south in winter or enjoy cruises, Seaside Escape offers refined and versatile pieces made to last beyond a single season. Some designs feature recycled Italian fabrics, reflecting our commitment to more responsible fashion.
