I'm loving the cat eye sunglass trend! I usually don't follow anything really trendy, but I love the retro feel to these. Pretty much every sunglass vendor out there now has a version or two (or three) of the cat eye - if happen to be at a department or a sunglass specialty store, try a pair on!
Kate Spade - Franca Cat Eye. Simple, nothing too crazy.
Ray Ban - Retro Cat Eye. Cool version of cat eyes, more rounded.
Gucci - Young Project Cat Eye. Looks great on (most people).
Prada - Rectangular Cat Eye, Different... they have another pair that is pretty unique, meaning: hard to pull off :)
House of Harlow - Chelsea Cat Eye
Alexander McQueen - Two Tone Cat Eye. My most recent purchase - loving them!
I tried on many pairs, the McQueens were my favorite :) at least for my face. Although I did say no more adding to my sunglass collection...
