I particularly love the almost aviator style wire frames (W16S) with the chic black lenses. It's a super cool twist on a classic shape. I'd pair these shades back with a wet look leather jacket, ripped jeans and patent leather boots. Very chic and edgy!
I'm also really into the thick acetate frames in tortoise shell with the wire bottom (W06V). They definitely make a statement! Unfortunately for me these won't suit my face shape, but I think the shape would work for a dapper gent in a tailored suit and some very white sneakers. I would definitely talk to that guy at a party.
