The petite Hart of Dixie actress looked every inch the fashion darling in a dazzling sequin minidress from the 3.1 Phillip Lim Holiday 2013 collection.
The show-stopping frock featured glitzy white, blue and green embellishment, along with a sheer V-neck mesh panel.
Zero accessories let her trophy dress do all the talking, while her deep brunette locks were scraped back into a low ponytail.
And she proved she's totally in tune with this season's metallic heels trend, adding inches to her 5'2" frame with platform peep-toes by Brian Atwood.
