With summer quickly approaching, swimsuits are on my mind. From the biggest swim trends of 2025 to the cool swimsuits sitting in my cart right now, I'm ready to discuss all things beach attire. That also includes the key designer swimsuit brands to have on your radar. Looking at the fashion set, there are some that are in heavy rotation and feel particularly suitcase-worthy if you're looking to make a summer splurge.
From buzzy designers like Isa Boulder to heritage brands like Chanel, a range of brands have landed on the designer swimsuit short list. Ahead, see the six designer swimsuit brands you'll spot on the fashion set this summer. The styles range from vibrant prints and cool cutouts to bikini pieces with satin finishes and classic lines, so you're sure to find something to add to your cart.
Christopher Esber
Christopher Esber may be known for his stunning cutout dresses and forward designs in the world of ready-to-wear, but he applies the same design prowess to swimwear. Bikinis simply don't get cooler.
Isa Boulder
Isa Boulder is instantly recognizable because of the swimwear's satiny finish and beautiful ruching details, making it the most glamorous thing you can slip into for a trip to the beach.
Chanel
Chanel swimsuits have always been big among the fashion set, but they have even more of a cult following thanks to the revival of '90s-inspired silhouettes. Opt for monochrome and classic Chanel branding.
Oséree
Another brand that is synonymous with luxe swimwear? Oséree. The brand's glittering swimsuits are a favorite on the fashion scene, as are its cool prints.
Matteau
When it comes to the peak of cool minimal swimsuits, Matteau is the brand to know. The Australian label has mastered simple lines and timeless silhouettes but also throws in season-defining trends.
Eres
It doesn't get more classic than Eres. The French brand's swimsuits are true investment pieces, so if you're looking to buy something now that you can own forever, this is what to order.
