You don't have to tell Iskra Lawrence how to work a swimsuit. The body positive model is the face of Aerie and has taken many bikinigrams under the sun. It was no surprise then, that the model shared a new snap of herself in a two piece swimsuit on Feb. 18. The bikini was from Aerie, of course, and Iskra paired it with Vogue Eyewear shades. She flashed a happy, closed-eye smile before posting the photo with a positive message in the caption. Read on to see Iskra's stripe bikini, then shop similar ones below.
