The Best Swimwear Brands for Summer 2025

When sunny days come, my fashion wish list has plenty of summer essentials, with some new swimsuits taking up the number one slot. Bikini and dress dominate my early season shopping list. Before I think about sundresses and shorts, the few days of sunshine in my bikini are essential for my pale skin. Plus, there’s something about narrowing down the best swimwear brands to set the tone for the entire season.

However, in the age of online shopping, exploring the perfect bikini can be much more difficult. It is often drowned at the deep edge of Google searches and social media scrolls. There’s a lot to navigate between trends, sizing and pricing. And don’t start the struggle to find a swimsuit that actually instills confidence. (I’m talking about the inevitable concern that your suit is either see-through or not fully supportive.)

The perfect swimwear brand for shopping in the summer of 2025

Personally, I have a hard time finding a suit that supports my big breasts and feels young and young. Of course, the suit’s additional factors are either too modest or too flashy. My list of requirements for a bikini is almost as loud as my 1 year old nie’s eating habits, so I can trust that I did my research. I’ve rounded up the best swimwear brand you’re dumping cover up and heading to the beach. Let’s jump in!

Best Accessories: Monday Swimwear

As someone who is blessed/cursed with big breasts, it often feels difficult to find a fashionable swimsuit that fits well. After years of buying an XL bikini top and paying for changes, I discovered a Monday swimsuit, but never looked back. Their swimwear is not only high quality and trendy, but also comes in a comprehensive range of sizes with adjustable tie fits and larger cup options. I’m also a sucker for matching sets and have a full run of matching accessories from salons to beach bags on Mondays.

Best Supporting Sizing: Hunzag

Sold as “original wrinkles,” Hunza G is essentially a sister-in-the-tourism swimsuit. All of their bikini and dresses are versatile. I know: it sounds impossible, but can only be explained by the fact that pixie dust is woven into the fabric. The ultra stretch fit is both supportive, comfortable and easy at the same time, and suits everyone I know. With no need to sweat oversized options, Hunza G is one of the easiest and best swimwear brands to shop online. Major bonus points for being sold as a set.

Best Sustainable: Anemones

I recently introduced Anemos and the brand quickly appeared on my short list of the best swimwear brands. Anemos is an LA-based apparel and swimwear destination with a focus on sustainability and minimalism. Their work is gorgeous and timeless, but what really sets the brand apart is that all the fabrics are sustainable and the packaging is 100% compostable. I can wear their bikini all these days throughout my trip to Cabo and prove their flattering and rich colorway.

Best Underwire: Onia

Although Onia doesn’t just swim, she is best known for her highly detailed swimsuit pieces. With a great fit and foam, you can trust that everything you buy from Onia is supportive, well-made and obviously surprising. I personally love their underwire bikini and one-piece style. They are fashionable and functional – and no, the underwire won’t dig into your skin!

Most trends: Monche

Mont is one of the brands that can be said to be of high quality just by looking at the work. Their swimsuits have an easy look while focusing on forward, trends and fit. They recently released their collection in collaboration with Olivia Culpo. Additionally, this brand must be one of the best swimwear brands as it was discovered at Taylor Swift.

Best Prints and Patterns: Agua Bendita

If you’re in the market for swimsuits that are beautifully crafted with unique patterns, look for Agua Bendita. Each swimsuit is handmade by female Colombian artisans, many of whom are home moms, and the passion they inject into their work is clear. Even if the pattern isn’t directed at you, their solid swimsuits are still top notch and unlike the rest on the market. Another reason why Agua Bendita is one of the best swimwear brands? They have kids swimsuit lines so you can match your little during the holidays!

Best size fit: cuup

When a swimsuit is made by an intimate company, you can trust it fits well, and Cuup is the perfect example. Their tagline is “We will support you” and after trying their swimming I will support them. With minimal design, these suits are suitable for all ages and the right person.

Best Timeless Style: Solid & Striped

You may know their recent solid and striped patterns Collaboration with Sofia RichieBut my obsession with the brand started a few years ago when I tried out a bikini in a store in New York. Their swimming collection has an ideal balance of trendy and timeless styles, while at the same time feeling high and youthful. Sofia Richie may draw you towards you, but that’s a swimsuit that you’re coming back more, mark my words.
