Are sunglasses the new handbag?

Sunglasses can change an outfit in an instant and they're not just for the summer months. Whenever I go on a trip I tend to buy a pair of sunglasses - it's part of my Heathrow routine and I'm very thrown off when I have to depart from Gatwick. At first I didn't really like wearing sunglasses: I felt like I was hiding something but now I wear a pair of Burberry Quilted Check sunglasses almost every day. I never leave the house without them. It's not so much vanity or even fashion, I just don't like the sun in my eyes.
