SALE UPDATE: Due to high demand during our Summer Sale, only a limited number of items are left!

The two-piece that gives you the confidence of a one-piece — with all the freedom of a bikini.

Tired of dreading swimsuit season because nothing ever feels quite right? The Danielle was made for the woman who is done compromising. Done with bikinis that dig in. Done with one-pieces that somehow make her feel more self-conscious, not less. Done with standing in a dressing room wondering if anything was ever made for a body like hers.

Every detail chosen with one woman in mind. The real one. Not the airbrushed version. The one whose body has lived, changed, and deserves to feel completely beautiful the moment she steps onto the sand.

Why women love the Danielle:

  • Tummy coverage that actually flatters. The relaxed tankini length skims and smooths without squeezing — the coverage you want, in a silhouette that moves beautifully with you all day long.
  • The freedom a one-piece never gives you. Two separate pieces mean a fit that actually works for your body. Mix sizes if you need to. Comfortable stretch everywhere else. Because a swimsuit that digs in is one you leave at home.
  • Built-in support where you need it. Structured enough to wear without a bra. Comfortable enough to wear all day. The Danielle holds everything in place so you never have to think about it again.
  • Stays exactly where you put it. Secure straps and well-constructed fabric that move with you through every swim, every walk, every moment worth enjoying — without a single adjustment.
  • A print and silhouette that work with you. Details strategically placed to flatter — not to draw attention where you do not want it.
  • Thoughtful details that make sense. Designed for real life at the water — not just the photoshoot.

Fit Guide: Runs true to size. Tankini styles offer the most tummy coverage. When in doubt — size up for more comfortable coverage. Tops and bottoms can be sized separately for the perfect fit.

Coverage, comfort, and the freedom to actually enjoy your summer. That is the Danielle.
