I have always bought cheapie sunglasses, which puts me at the mercy of whatever is typically trendy at Target. That said, I'm upping my personal style quotient, and I'm looking for something a little more classic and a little less trendy. Trouble is, I have no idea what kind of sunglasses are appropriate, and I still don't want to spend a shit ton of cash. Any recommendations for this ugly mug? I have no idea what my "head shape" is. Mrs. Sheep says "block" but I'd like your opinions.
