Aside from having light sensitive eyes, sunnies are essential to my everyday ensemble. They are the one accessory that I will go home to retrieve if ever forgotten. But not any frame will do; I have penchant for exaggerated cat eye sunnies. I have been rocking them for a couple of seasons now, but it seems they have really caught on with the everyday woman (antifash speaking). Although I would like to splurge on this pair and that pair, I also enjoy eating more than just Ramen noodles every meal. The appetite always seems to win.
You can find most of these sunnies at ASOS.com, with the exception of the top and bottom right pair (links provided).
Oh, and they are all under 50 bucks ;-)
