But today at the official photocall for Wall Street: Money Never Sleeps, Mulligan looked gorgeous on the red carpet.
Mulligan decided to dress it up a bit and wore a gorgeous purple RM by Roland Mouret Pazeau dress.
Even the back of her dress looks great.
Carey finished the look with some Fendi stilettos.
We're loving her entire look today. Hopefully she keeps up the glam and leaves the casual look for another time.
