2018 Best Party Dresses

Saks Fifth Avenue

Nothing kills a night faster than wearing the same outfit as another guest. The vast selection of eveningwear at Saks, however, makes it easy to avoid that social snafu. If your invite dictates cocktail attire, peruse the flirty styles from Delfi Collective and classic silhouettes from Diane von Furstenberg on the first floor. Dressing for a black-tie gala? Head to the designer boutiques upstairs and choose among Fendi, Valentino, and Prada.
