What a pleasant surprise from Jennifer Aniston!
The actress eschewed her usual black for a beaded and colorful slinky little Roberto Cavalli gown at the Office Christmas Party premiere in LA Wednesday, and it looked fantastic on her!

We're so in love, we just can't stop staring!
Olivia Munn and Katy Perry also attended the red carpet event, both of them looking gorgeous.
The X-Men: Apocalypse star slipped into a white, crochet-detailed Jonathan Simkhai number with tiered ruffles along the skirt, while the 32-year-old gave Ava Gardner teas in a mock-neck black gown with high leg slit.
Katy also had the hands-down best accessory of the night — a square clutch that featured her Hollywood Walk of Fame star on it! So cute!
