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.

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.

The top that works for every body. The Anani has a sporty scoop neck silhouette that holds you in and looks genuinely good doing it.

No adjusting, no slipping, no thinking about your top once you are in the water. The kind of piece you reach for whether you are surfing, at the pool or heading straight to lunch after.

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.
