Celebs love Lisa Marie Fernandez swimwear, whether it鈥檚 Nicole Richie wearing her gold bikini while boating in Cannes, or Rihanna sporting a blue-and-white one-piece by the designer during last year鈥檚 Fourth of July (not to be confused with the time she wore a scarf as a bikini top). Now Lisa Marie Fernandez has come up with a new genius idea: bikini cardigans.

Fernandez designed the Bikini Twin Set for women who don鈥檛 want to get too much sun or don鈥檛 like to show their arms, Fashionista reports. 鈥淵ou鈥檙e sitting at a pool somewhere or it gets chilly at the end of the day. Or not and you just want to go swimming in it 鈥 it鈥檚 the same exact material [as the bikini],鈥 she tells the website.

The set comes with a matching bikini top, bottom and cropped cardigan, and you can bet you鈥檒l be paying celebrity prices for the trendy beach must-have. The Genevieve Twin Set in seersucker, for example, is listed on the designer鈥檚 website for $605. But the cardigan is worth the price because of its dual purpose, Fernandez tells Fashionista. Outside of the beach, it can also double as a cardigan over your tank top or dress for a perfect summer ensemble.

If you鈥檙e feeling the bikini cardigan, head over to the designer鈥檚 website to check it out. And soon, the twin sets will also be available at Net-a-Porter, Matchesfashion, Shopbop, Saks Fifth Avenue and Barneys, Fashionista says.

We expect to see a lot of cardigans on the beach this summer.
