12 Retro Dresses Under $50

Call it the Mad Men effect, but nothing quite beats those sweet, feminine frocks from the '50s and '60s to stylishly combat the summer heat. From mod shifts to flirty halters, the dresses of these eras have been popularized by plenty of young-and-nostalgic performers, including Lana Del Rey, Z. Berg, and Zooey Deschanel, the queen of vintage-y dresses. (Not only does Zooey wear them frequently in real life, but also on her hit sitcom, The New Girl.)

Zooey and Lana might be retro-cute, but If the idea of wearing actual vintage doesn't appeal to you, it's easy to find the modern interpretations of the style—even if you're on a budget. We've rounded up a dozen affordable dresses—$50 or fewer, to be exact—that look vintage, but feel brand new.

It's like the dress that Zooey wears in the New Girl intro, except sparkly and therefore more awesome.
