For the past few years, it seems like everyone's been jumping onto this retro bandwagon.
With Louis Vuitton's fall collection showing '50s inspired clothes - check out those long skirts - you know it's here to stay...for at least a little while longer.
I think you should wear what feels right for you... I like some of the 50's stuff and some of the retro is neat, I'm a fan of aviator sunglasses so I have no issues with it.
