Bikinis that actually stay on you while you surf

I haven't tried these out yet myself, but my friend suggested them to me. They look like they'd work, and they're cute to boot. Almost every time you see a woman surfing, you see her readjusting her two piece as she carves out a line. Still, nothing beats surfing in a bikini. I usually just wear two and hope that one sticks. I think I'll give one of these a shot.
