Despite keeping her look low key, Rose Byrne still oozed oodles of glamour on the red carpet at the “X-Men: First Class” New York Premiere tonight.

She opted for super sexy Marc Jacobs Fall 2011 navy lace dress.

The long sleeve dress was of course lined, but we still get to clearly see the bold lace details.

Many of you haven’t warmed to Rose’s blunt bangs, so you’ll be pleased to see she opted for side sweeping bangs with her beehive ‘do.

A navy satin Kotur J.B. Renna Karung clutch, Cartier jewels and nude Brian Atwood pumps completed this stunning BDOTW worthy look.
