FAQ

Use the Find my size tool on each swimwear page: enter your measurements and we suggest the right size for that style. You can also check our size chart, which includes UK, US, EU and AU sizes.

Measure yourself in underwear, with the tape flat and snug but not tight. Bust: around the fullest part. Waist: at the narrowest part, above the belly button. Hips: around the fullest part of your hips and bottom.

Yes. Pieces from The Canvas collection run small, so we suggest the next size up. The Find my size tool already takes this into account.

Of course. Tops and bottoms are sold separately so you can choose the perfect size for each.

Our swimwear is crafted from a blend of 85% polyester and 15% spandex, certified Oeko-Tex: soft, supportive and skin-safe. Pieces are fully lined.

Hand wash in cold water with a mild soap. Lay flat to dry in the shade. Avoid rolling, twisting or leaving it damp for too long, and do not tumble dry, iron, bleach or dry clean. Keep it away from rough surfaces and harsh pool or spa chemicals.

Every piece is designed in-house and handcrafted in our atelier in Montréal.

We work with freshwater pearls, crystals, natural stones and mother-of-pearl. Each natural material is unique, so shape and shade can vary slightly from one piece to another. Learn more on our care instructions page.

Avoid contact with perfume, lotion and cleaning products, which can dull pearls and stones. Protect your pieces from scratches and shocks, and store each one separately in a soft pouch. Pearls love to be worn: contact with the skin helps keep their natural lustre.
