Ray Bans are good. I've had a couple of pair over the years. I know have a pair of Maui Jims that I really like.
I wouldn't buy my wife a pair of sunglasses because the fit and look can vary quite a bit from person to person and style to style. Make certain Ms.Wacky really loves them, and if not, bring her back to buy a pair that she does love.
Hey, on another note, are you coming to TCU!?!?
