Ever since actress Megan Ferguson told us about the Left on Friday one-piece that “lifted all that could be lifted” while still allowing room for snacks, we can’t seem to escape the brand’s suits. Yeehawt’s MacKinley Jade Lutes-Adlhoch told us she swims laps in her LoF one-piece, and brand consultant Lucy Litman likes that the brand’s bottoms stay in place — exactly as they should. Even Strategist writer Arielle Avila counts the bikinis among her favorite swimsuits for surfing and swimming. Given Left on Friday’s extensive fan club, we thought it was time to give the swimsuit line a proper test.

Between the two of us, we tried 16 of Left on Friday’s swimsuits and two cover-ups. In general, we found the suits were formfitting and thick, so thick that it took water several seconds to breach the fabric. Another feature worth mentioning: None of the suits are padded in the chest, so you’ll want to wear waterproof pasties if you’re worried about any, well, nipple appearances. Many of the suits are available in upwards of 15 colors, so this isn’t as much of a concern with the darker colors. As for sizing, many Left on Friday enthusiasts recommend sizing up. For context, Bella, who is five-three with a short torso and is usually an extra small or small, tried the suits in a small. Liza, who is five-seven and usually wears a size medium for tops and medium or large for bottoms, tried them in a medium.
