Gucci Jackie O's
I love Jackie O sunglasses for two reasons. The first is that I hate those little plastic nose rests you get on metal framed sunglasses, and this style never has them. The second is that I have the kind of face that looks better covered up, and Jackie O's are big. Since I cracked the lenses on my old pair, I'm currently contemplating splashing out on these Gucci ones to replace them. £45 is actually quite reasonable for designer sunnies.
