It's all about what fits both your style and your face. You're going to be wearing them for a looong time, so there's really no substitute for going out and trying on frames. But if you post a picture and a bit about what you're looking for, I'm sure we can give you a few ideas that will get the ball rolling.
Meanwhile, for what it's worth, I'm particularly impressed by some of the frames I've seen from Lanvin and Yohji Yamamoto. And purely for the amount of obsessive detail, Chrome Hearts.
