NEW IN SPRING 2026

River Nineties Blue Top

Regular price $86.00 USD
Sale price Regular price

You want something with a little more edge than a basic bikini top. The River has a sporty retro cut with contrast binding that makes it stand out without trying too hard.

The fit is secure, the adjustable straps lock it in place and the removable padding gives you exactly the shape you want. It looks just as good walking off the beach as it does in the water.

Isla Riviera Peach Stripe One Piece

Regular price $178.00 USD
Sale price Regular price

The one piece you reach for on repeat. A scoop neckline front and back with a high cut leg that elongates and flatters your body. It fits like it was made for you and stays put whether you are surfing, free diving or just living your life in it.

One of those suits that looks just as good with jeans and a pair of sandals as it does in the water.

More coverage, real support and still genuinely cute. The Maya has underwire that actually works — the most comfortable underwire bikini top you will put on. No digging, no rubbing, no adjusting. Just a flattering retro silhouette that holds you in and stays exactly where you put it all day.

Vai Nineties Blue Bottom

That 90's energy but make it surf ready. The Vai is a high hip cheeky bottom with contrast binding that hits that sweet spot between retro and right now. The cut elongates your legs and sits exactly where it should. 

Confident, flattering and secure enough to actually surf in. One of those bottoms you just feel really good in.

DESIGNED TO MOVE WITH YOU.

We are on a mission to empower women through movement, community and conscious choice.

When you feel good in what you're wearing, you show up differently. You go harder, stay longer, say yes more often. That's what SEPTEMBER is built for.

We design swimwear for women who don't separate their style from their strength. Pieces made to move with you, from the beach to wherever the day takes you. Every decision we make, from the fabrics we source to the factory we work with, is rooted in doing things the right way.

Because the ocean deserves it. And so do you.
