Why We Love It: Feminine classics feel fresh again this season. Designers put a quirky twist on vintage silhouettes like nipped in waists, poufy skirts and brooch-inspired necklaces this season that are perfectly party ready.

Pair It With: Embrace the retro trend by wearing your full skirt with pumps and a button-up, or for something more subtle, grab a pair of cat eye sunglasses or a rhinestone brooch that will add a touch of vintage to an otherwise modern look.
