What's rad? Ruching, that's what. It's an ancient sewing technique, and it's flattering powers are undeniable. Especially when it comes to a sexy, hot LBD with rad black ruching. If you don't already have one of these quick fix, every-occasion frocks, I suggest you consider. Look at how stunning Emmy Rossum looks in her architectural Emanuel Ungaro; she doesn't show a lot of skin, but it's somehow seriously sexy. OK, her black gladiator Stuart Weitzman sandals may have something to do with it too . . .
