Even though summer's over, you still need to beware of those UV rays when you head out on that Caribbean cruise this fall. That's where this pricy ($99) Solestrom SmartSwim UV Intensity Bikini might just save your life (or the life of that comely companion of yours). Its attached beads are sensitive to sunlight, and turn a darker purple as they're exposed to more UV rays.

As you've probably already noticed, the beads are affixed to the string holding up the bikini bottoms, and on the bra, too, all constantly on a heroic vigil for those deadly skin cancer-causing rays. If you're wearing such a suit, we're thinking it's not going to be too hard to enlist someone's support in keeping an eye on the exact shade of those beads, certainly worthy of the closest scrutiny.
