2 Dresses, 1 Night: Comic-Con Edition!

Sometimes, one dress just isn't enough -- especially when it's Comic-Con, one of the most fun and highly anticipated events of the year!

Check out the outfit changes of these fashionable stars.

The ever-stylish Ginnifer Goodwin looked comfortable in a loose-fitting white Derek Lam dress at the Once Upon a Time Comic-Con panel on July 20, then later changed into a dark green sleeveless Vionnet dress at the annual Entertainment Weekly Comic-Con Celebration party.

The always risk-taking Hailee Steinfeld sported a high-waisted, black-and-white menswear inspired ensemble to the Ender's Game panel. She later let her hair down and changed into a more feminine mixed-prints get-up for the Summit Entertainment party.

Shailene Woodley was also in black-and-white for the Divergent panel, before showing off her new blonde 'do in a chic all-black outfit at the star-studded Summit Entertainment party.

Nikita star Maggie Q rocked a black floor-length maxi dress at the Divergent panel, before turning plenty of heads in a super-short silver jumpsuit at the Summit Entertainment party.

Zoe Kravitz kept it casual in a t-shirt and jeans at the Divergent panel, then changed into an effortless edgy all-black get-up at the Summit Entertainment party.
