Tis the season for beach trips! And who better to get a little swimsuit style inspiration from than SI Swimsuit Rookie of the Year Kelly Rohrbach

Known for her love of the beach, Kelly must have 1000 swimsuits to choose from. But it wasn't until she whipped out this sexy one piece and shared it for the world of Instagram to see, that our eyes were opened to the sex appeal a onsie can actually have! 

Ideal for a casual day at the beach or even a day date on a yacht (a girl can dream, right?), this suit can easily be paired with a pair of cutoff shots, reflective sunnies and some metallic flips flops for a casual, yet chic, daytime look. Take it from us, if Kelly Rohrbach says denim shorts are sexy, then they most definitely are.
