With sunny days ahead, my fashion wishlist is full of summer essentials, with a few new swimsuits occupying the number one slot. Bikinis and one-pieces dominate my early-season shopping list. Before I even consider sundresses or shorts, a few days soaking up the sun in a bikini are essential for my pale skin. Plus, there’s something about narrowing down the best swimwear brands that sets the tone for the whole season.

However, in the age of online shopping, the quest for the perfect bikini becomes that much harder. It often leaves me drowning in the deep end of Google searches and social media scrolls trying to find out how a swimsuit will actually fit, feel, and look. Between trends, sizing, and pricing, there’s a lot to navigate. And don’t get me started on the struggle of finding swimwear that actually instills confidence. (I’m talking about the inevitable worry about your suit being see-through or not supportive enough.)

For me personally, I struggle with finding suits that are supportive for my larger chest and still feel young and youthful. Of course, there’s also the added factor of the suit also being too modest or too showy. My list of requirements in a bikini is about as picky as my one-year-old niece’s eating habits, so you can trust I’ve done my research. I’ve rounded up the best swimwear brands that’ll have you ditching the cover-up and heading for the beach. Let’s dive in!

Best Accessories: Monday Swimwear

As someone who is blessed/cursed with a larger chest, it can often feel difficult to find fashionable swimsuits that fit well. After years of purchasing XL bikini tops and paying for alterations, I discovered Monday Swimwear—and never looked back. Their swimwear is not only high-quality and on-trend, but is also offered in an inclusive size range, with adjustable tie fits and larger cup options. I’m also a sucker for a matching set and love that Monday has a full run of matching accessories, from sarongs to beach bags.

Best Supportive Sizing: Hunza G

Marketed as “The Original Crinkle,” Hunza G is essentially the sisterhood of the traveling swimsuits. All of their bikinis and one-pieces are one-size-fits-all. I know: sounds impossible, but can only be explained by pixie dust being woven into their fabrics. The ultra-stretch fit is simultaneously supportive, comfortable, and effortless, looking good on everyone I know. With no need to sweat oversize options, Hunza G is one of the easiest and best swimwear brands to shop online. Major bonus points for also being sold as a set.

Best Sustainable: ANEMOS

I was only recently introduced to ANEMOS, and the brand has quickly made its way onto 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 pieces are gorgeous and timeless, but what really sets the brand apart is that all of their fabrics are sustainable and their packaging is 100% compostable. I wore their bikinis all throughout my recent trip to Cabo and can attest to their flattering fits and rich colorways.

Best Underwire: Onia

While Onia offers more than just swim, they are most well-known for elevated, detailed swimwear pieces. Combining great fit and form, you can trust that anything you purchase from Onia will be supportive, well-made, and, obviously, stunning. I’m personally obsessed with their underwire bikini and one-piece styles. They are fashionable and functional—and no, the underwire doesn’t dig into your skin!

Most On Trend: Montce

Montce is one of those brands that you can tell is high quality just by looking at their pieces. Their swimwear has an effortless appearance, while still being fashion forward, on-trend, and fit-focused. They recently released a collection in collaboration with Olivia Culpo, and I’m quite literally drooling over the feminine black and white look. Plus, the brand has been spotted on Taylor Swift, so it’s gotta be among the best swimwear brands.

Best Prints and Patterns: Agua Bendita

If you’re in the market for beautifully crafted swimwear with unique patterns, look no further than Agua Bendita. Each swimsuit is handmade by female Colombian artisans, a lot of whom are stay-at-home moms, and the passion that they infuse into their work is clear. Even if patterns aren’t for you, their solid swimwear is still top-notch and unlike anything else on the market. Another reason why Agua Bendita is one of the best swimwear brands? They have a kids swimwear line, so you can match with your littles on vacation!

Best True-to-Size Fit: CUUP

When swimwear is made by an intimatewear company, you can trust that it will fit well, and CUUP is the perfect example. Their tag line is “We support you,” and after trying their swim, I support them. The minimal designs make these suits suitable for all ages and anyone that puts fit first. Not sure what size to get? Take their size test for an accurate recommendation!

Best Timeless Styles: Solid & Striped

You may know Solid & Striped from their recent collaboration with Sofia Richie, but my obsession with the brand started a few years ago when I tried on a bikini in their New York storefront. Their swim collection has the ideal balance of trendy and timeless styles, and feels simultaneously elevated and youthful. While Sofia Richie may draw you in, it’s the swimwear that will keep you coming back for more, mark my words.
