Lately, I'd been thinking that current sunglasses seem to be a whole lot more adventurous than current spectacles. Then I saw Ksubi's 2012 collection and was filled with joy.
I want this pair. They're called Sigma:
Online store Eyegoodies sell both Ksubi sunglasses and glasses. (By the way, I'm not affiliated with Eyegoodies, but I think they're lovely. They gave me a discount on my Karen Walker sunglasses after I had already submitted my order at full price!)
Edit: Occhiali in Auckland also sell them.
