... several of the sunglasses seen in the Dolce & Gabbana Spring 2013 campaign:
I thnk these are so adorable, they would make a nice addition to any sunglass collection. And while I have over 20 sunglasses already (you can see some of them here and here, for instance), I don't have anything that even remotely resemble these so far. So I do think getting these would be kind of justified in my case!
