Frequently Asked Questions

Matching perfectly has never really been our thing.

Oh Sea was designed to be mixed, styled, and worn your way. Different colors, different textures, different moods. The beauty is in making it feel authentic and personal.

Cut and sewn in California, with imported materials.

Every Oh Sea piece is designed and produced locally in small runs because quality, craftsmanship, and keeping things close to home matter to us.

Most Oh Sea restocks happen within 4–6 weeks, depending on the style and fabric availability.

Our swimwear runs slightly skimpier by design. 

If you prefer more coverage or are between sizes, we recommend sizing up.

You can reference our size guide for exact measurements and fit details.

Nope, and intentionally so.

All Oh Sea tops and bottoms are sold separately in sizes XS-XL, so you can mix sizes, colors, and fits however you want. Because the perfect fit rarely comes in a perfectly matching set.

Our pieces are made using a blend of nylon, recycled nylon, spandex, stretch denim, and cotton, depending on the style.

Select collections, including our terracotta and red sets, feature chlorine-resistant, UV50+ protective, and antimicrobial fabrics designed to hold up beautifully wear after wear.

We recommend handwashing or machinewashing in cold water on a gentle cycle. Then, lay flat or line-dry. Tumble dry low when needed.
