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-eyes smile before posting the photo with a positive message in the caption. Read on to see Iskra's striped bikini, then shop similar ones ahead.
