Over the peplum yet? The A-list certainly seems to be. Everywhere you look, celebs are stepping out in super-sleek and fitted midi dresses that would do "Mad Men" bombshell Joan Harris proud. Short mini dresses are the obvious choice for a sexy look and floor-length numbers are a given in the classic glamour department, but celebs are realizing that midi dresses fall somewhere in between and deliver the best of both worlds.

With curve-hugging fits, interesting necklines, pop colors and punchy patterns, versatile midi dresses cover a lot of style territory: office appropriate, sexy date night, runway chic, fun and bubbly. And, most important of all, they're always flattering.

"Downton Abbey" actress Michelle Dockery proves you can never have too much plaid (or too much color) at Audi's Golden Globes Weekend event in Los Angeles when she stole the show with this vibrant Altuzarra midi dress.

Goth never looked so good. Actress Melonie Diaz embraced minimalism at the New York Film Critics Circle Awards by letting the delicate straps on her chic Cushnie et Ochs midi take center stage, pairing it with a vampy lip, dark nails and classic black pumps.

The midi hemline on Lucy Hale's Garbiela Cadena dress balances out the one-shouldered cut and bold galactic floral print for a look that's sophisticated enough for the red carpet of the 2014 People's Choice Awards, yet still fun and fresh for the "Pretty Little Liars" actress.

The ruching on Sarah Rafferty's Rhea Costa dress adds subtle volume to accentuate her waist, giving her a flattering shape and streamlined look for at Audi's 2014 Golden Globes Weekend event.
