Go and get yourself some cheap sunglasses:

I really love my Ray-Ban Wayfarers. I wear them all the time. I'm hopelessly devoted to them. Always will be. But sometimes there's nothing like a pair of cheap plastic sunglasses in a bright color to shake things up. Right now, I'm loving these ($10) for their round shape and pop of color. I think they were technically more spring/summer glasses but I can really appreciate the interest they bring to my fall/winter wardrobe (which tends to be more drab, anway):
