I’m pretty sure Mara Hoffman makes the most beautiful swimsuits at the moment. Her vibrant prints exude summer and her silhouettes are super flattering. Of course, I’m always attracted to the risqué cutout ones, except they are a rarely a good idea (for example: once you sit down, everything turns to mush). But this particular shape is smart — the one-piece-meets-two-piece — and the black band accentuates the most important part of the body (when it comes to swimsuits), the waist.
