Chic summer dressing means just the right amount of skin-baring: an exposed shoulder, a little leg, some decolletage. But this season, it's all about the back. I'm inclined to work this trend with these backless wonders by Saylor (similar to above), Stella McCartney (which I recently wore to a Malibu bash!), Giamba, Victoria Beckham, Asos, Club Monaco and Theory.
P.S. You might need a special backless bra like this to pull off these looks!
