The #1 Dress Style to Pack for Vacation 

I'm on a perennial quest to get become a more efficient packer—but the fact that I had to wheel two carry-ons through the airport on a recent trip should tell you that I haven't been particularly successful. One item I've found to improve matters significantly, however, is a good slip dress—particularly a black one, as it's pretty much immune to stains (or so I like to tell myself).

Plus, with all that room you save by bringing a couple of dresses that fold up into teeny-tiny squares, you can pack an extra pair of shoes or a cute clutch to wear with them. As Zoë Kravitz demonstrated on a recent holiday in Rome, slip dresses are the perfect neutral backdrop to a whole range of accessories. Dress them up at night with some statement earrings and a pair of high-heel sandals, or wear them for the daytime with a bandana and your favorite cat-eye shades. And if you happen to be going somewhere a little chillier—or just want to shield your shoulders from the sun—a slip dress is just as cute with a T-shirt layered underneath.

Below, see how Zoë styled the trend (don't worry—we won't blame you if you copy her look) and shop some of our favorite black slips in time for your next summer vacay.
