I Tried Reformation's Gorgeous New Swimwear—These Are the Pieces I'm Obsessed With

By Swedan MargenMay 6, 2025

When I'm looking for something reliable and chic—pared back but still elevated—Reformation is always an obvious choice. Case in point: When I needed a minimalistic, timeless wedding guest dress, it was the one of the first brands I checked. (I ended up going with the Casette Dress in black, which I still love.)

The brand's clothes tend to feel effortless yet elegant—like you just threw it on and somehow look put-together. Having perfected the in-between of elevated and relaxed, its pieces are the kind you wear over and over.

I loved the brand's recent expansion into sleepwear with its pajama launch, and its collaboration with Devon Lee Carlson was, of course, highly talked about. When I found out Reformation also makes swimwear and just put out its first seasonal swim collection of 2025, I knew I had to try it. Here's what I thought.

What I Tried

Vicky Bikini Top and Douro Bikini Bottom in Black Fior

Douro Bikini Bottom

This is the first one I tried on, and I'm not even exaggerating—my first unfiltered reaction in my head was literally "Wow." The fabric is extremely soft in a way I wasn't expecting. (It's made from EVO by Fulgar, a biobased fiber.) The bottoms have a cheeky coverage and mid-rise, and the set comes in three other colorways: Fior Lipstick, Lipstick Midnight, and Midnight Lipstick. It looks so chic on, and this was the swimsuit I ended up keeping.

If I had to pick just two favorites, they'd be this one and the contrast-trim set, without a doubt. I love the sweet blue with the lace trim and underwire. I've been thinking about it ever since I tried it on, and honestly, I might go back for it.

Azores Bikini Top and Faro Bikini Bottom in Black

I always gravitate toward black bikinis, and this season, I've been obsessed with swim shorts, so this one was very much my vibe. The top is a classic string-tie bikini, but it definitely feels higher-quality. Fit-wise, I'd recommend sizing up on the bottoms if you're between sizes or just want a little more coverage.

This one felt so good on—super flattering and comfortable. I love the cherry red too. I'm not big on high-waisted bottoms for myself, but if that's your preference, this set is definitely the one for you.
