THE TANKINI THAT MAKES EVERY MOMENT BY THE WATER YOUR OWN

There's a real confidence that comes from swimwear that simply works — and this two-piece tankini set delivers it without fuss. The gathered tank top skims gently over the tummy and hips, while the racerback design provides reliable support across the shoulders without restricting movement. Paired with bold polka dot swim shorts, the whole set has a playful, confident character that feels genuinely good to wear — from the poolside to the beach and everywhere in between.

WHY WOMEN LOVE IT

  • A gathered tank that flatters quietly and confidently. The softly gathered front panel skims smoothly over the tummy and hips, creating a balanced and quietly reassuring silhouette. It covers without hiding and flatters without trying too hard — the kind of design that simply makes you feel good.
  • Racerback support that holds everything in place. The clean racerback upper provides reliable support across the shoulders and back throughout the day, whether you're swimming, walking the seafront, or relaxing on a sunlounger. Secure, comfortable, and quietly sporty without being restrictive.
  • Polka dot shorts that bring a joyful touch. The bold polka dot pattern on the swim shorts adds a playful, feminine character to the set that pairs beautifully with the clean tank above. A co-ordinated set that looks intentional rather than thrown together.
  • Tummy-control fit for genuine confidence. The structured, supportive construction holds everything comfortably in place, creating a smooth and balanced silhouette from every angle. The kind of swimwear that lets you stop thinking about how you look and start actually enjoying the water.
  • Four colours, sizes S through XXL. Available in Light Blue, Black, Dark Blue, and Red — each colourway bringing its own confident character. Pair with a floaty cover-up and sandals for a complete beach look, or simply enjoy it exactly as it is.

The Hartley Sisters

Some dreams start with two sisters and a crazy idea. ✨

This year, we're celebrating our very first anniversary. 🤍
