There are two way to approach the use of pieces from last century in contemporary home decor. The first is to create a mix with modern and vintage design, the second is to set a reproduction almost perfect of an home of 50s or 60s. The results according to me are really different, I prefer the first way with no doubt.
In the same way I don’t like a woman dressed like a perfect 40s pin-up or like a reborn Jackie Kennedy, but I really love a modern apparel enriched by some vintage element.
It’s also true that  in recent years there is a big trend in the design itself, a great part of new furniture or lighting is designed in a distinctly retro style.
This fact makes more complicates to create interior with a well-balanced mix, but it's still possible.
