The one piece you actually want to be seen in. The Tahora has a scoop neck front and a deep open back that makes it feel sexy without trying too hard.

You know that feeling when a top actually holds you in, looks good and you stop thinking about it the second you put it on? That's the Moana.

The square neckline and wide straps give you real support without the sports bra situation. The crinkle fabric is unlike anything else in your swim drawer. Textured, substantial and honestly kind of addictive to touch.

FABRIC IS RECYCLED NYLON 'CRINKLE' MATERIAL. Please look closely at the photos for the texture of the fabric.

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.
