Summer is already in full swing, and Kendall and Kylie Jenner are diving right in with a swimwear collection with REVOLVE. The line holds 23 pieces, from mix-and-match bikinis to one-pieces, but they’re mostly all itty-bitty — “swimtimates,” they call them.

The barely-there aesthetic in the range is channeled from the sisters’ own styling preferences, as they told Vogue:

“I’m definitely a fan of the ‘swimtimates’ trend! I love layering lingerie and swim into my everyday looks, especially during the summertime.” Kylie is also on board. “I think swimwear sometimes has a lingerie feel to it, so it only makes sense that people combine the two clothing styles together,” she says.

The two-pieces are neon, white and red-hot, while camo is the only print to make a splash on a one-piece. The Kendall + Kylie x REVOLVE capsule is available to shop online now.
