Kendall and Kylie Jenner launch first swimwear line

LOS ANGELES, June 9 (UPI) -- Reality star siblings Kendall Jenner and Kylie Jenner have launched their first swimwear line.

The sisters released their Kendall + Kylie swim collection for Topshop on Thursday after announcing the project in April. Kendall, 20, and Kylie, 18, both shared photos from the line on Instagram.

The Kendall + Kylie collection is available in select Topshop and Nordstrom stores and ranges from $30 to $85. The 37-piece line includes colorful one-piece swimsuits, bikinis and bondage-style monokinis.

"With every new collection we create, Kylie and I are always looking for a challenge and to evolve our experience," Kendall told Topshop. "Swimwear is a must for summer so it's exciting getting to make an exclusive collection ... and have some fun with it."

"Being raised in California our whole lives, we definitely love the beach and the sun," Kylie added. "We wanted to capture the beachy L.A. summer vibe but put our own special twist on it. We picked lots of bold shades and prints to create the line and make it unique."

Kendall and Kylie launched their first clothing collection for Topshop last June after previously collaborating on a line for PacSun. Kendall is also busy with her modeling career, while Kylie oversees her popular lip kit line.

"I just really want to be a businesswoman," Kylie said in the December issue of Interview.
