Choosing the right bikini is about more than just a size—it's about finding a shape that transforms how confident and comfortable you feel at the beach. With new trends emerging for the upcoming season, the OCEAN MYSTERY team has created the ultimate guide to 2025 swimwear.
Whether you love minimal tan lines, need supportive fits, or want to experiment with bold new colours, here is everything you need to know to elevate your beach wardrobe.
Triangle Cuts: The Versatile Classic
The classic triangle silhouette continues to dominate 2025, serving as the go-to for sun seekers who prefer minimal tan lines and a sleek finish. Whether you prefer string ties, fixed bands, or daring micro shapes, this cut allows you to customise coverage without compromising on style.
Browse our full range of adjustable styles in the Triangle Bikini Tops Collection.
Halter Cuts: Lift & Support
Halter styles remain the top choice for women desiring extra lift and upper-body security. The tied-neck structure creates a naturally lifted shape that is ideal for both lounging and active swimming days.
Explore our most supportive pieces inside the Halter Bikini Tops Collection.
Bralette Cuts: Sporty & Chic
Bridging the gap between swimwear and lingerie, bralette tops have become a modern essential. Thanks to their comfort, natural shaping, and sporty silhouette, ribbed bralettes and clean longline shapes are gaining strong momentum for 2025.

2. How to Choose the Right Fit for Your Body
Not sure which cut suits you best? Use this quick cheat sheet to find your match.
For Smaller Busts
Look for minimal cuts, micro triangles, and soft-lined bralettes. These styles offer natural lift without overwhelming your frame. Adjustable sliding triangles are particularly effective as they allow you to control the width of the cups to create the illusion of fullness.
For Larger Busts
Prioritise structure. Supportive halter tops, thicker shoulder straps, and longline bralettes providing an under-bust band offer security and a balanced silhouette. Look for reinforced bands or adjustable ties that allow you to customise the tension for a perfect fit.
For Curvy Hips or Petite Frames
It’s all about the leg line. High-leg bikini bottoms work wonders to elongate the legs, while side-tie shapes allow the flexibility to adjust the rise to sit comfortably on your hips without digging in.
