Retro Sunglasses

Retro Sunglasses consist of all the greatest attributes of sunglasses from shapes to eras.  Small metal details, unique and very distinct shapes that take us back thru all the decades from the 1950's all the way through the early 2000s.  Retro Sunglasses represent the throw back era, a little retro funk, and the obvious retro vibes.  Which retro style of glasses brings you back?
