Matte black sunnies? Yes please. Great complement to an all-black outfit for you summertime goths.
Kristina and I agree that this pair really brings to mind some 60s Italian cinema. I'd totally wear them while lounging on a boat in Venice in a matching Audrey Hepburn-esque striped boater dress (like this one).
Clear wayfarers are also a great option. They go with anything and are kind of futuristic at the same time!
Ultimate favourite is always the tortoise shell though. These babies always look so good in the sun with a pair of cut-offs and maybe some Nina Z clogs. But hey, at $19-24 you can afford to get 2 pairs for sure!
