SmartSwim uses

October is the PERFECT time to tell you about the SmartSwim bikini from Solestrom. Why? Because with the weather getting chilly, fast, it’ll be months before you see a sight like this in real life. The fact that the beads on the bikini ties and bra color-change to indicate the amount of harmful UV rays you’re being exposed to is a neat idea, but unless you think THAT girl is going to carry her color-coded cheatsheet with her to the beach while she’s laying around showing off her SmartSwim ($99) and other, um, paid-for-assets (more than $99), Solestrom might want to consider having them change color altogether.
