I Love My Dita Pushers

I hardly ever buy anything expensive or "luxurious", but I really love my Dita Pusher sunglasses. I got them for 1/10th normal price because I had a friend who worked for Dita when I lived in Los Angeles and he gave them to me for my birthday a couple of years ago. I've got a big head, and these are some of the only glasses that have ever felt comfortable for me. Alas, despite taking good care of them they're starting to wear out. I'm not sure what I'm going to do. I really can't justify spending hundreds of dollars to replace them. Sigh.
