The piece: Cosabella Glow-in-the-Dark Underwire Bra  and Hotpants 
The price: $101 and $59
Why we want it: I'm a sucker for pretty lingerie — and one that actually glows in the dark? Too awesome to pass by. A could-be cheesy concept is executed brilliantly by Cosabella , with ladylike lace and a sophisticated cut that looks pretty awesome on its own, sans glow. And unlike an earlier version that reacted to a black light, these function like your regular glow-in-the-dark items, absorbing enough light in under five minutes (from the sun or a bulb) to glow when you turn the switch off. Dubious? I was, too, but I tried out a set, and I'm not even exaggerating when I say it was magical.
