I don't know about you, but I really dig quirky shades. I have been slowly growing my own collection (a picture of my way-cool Prada shades can be seen here) and wouldn't mind adding these to my scant collection. All of them (from what I can see, at least!) feature mirrored shades that are really nice and refreshing to see on a hot summer day.
I'm particularly fond of the top two pairs, because I can't stay away from cat-eyes. Meow.
