Keira Knightley became a mom one year ago, but the stylish star's glow has yet to subside. The actress stepped out in Rome Sunday in a cut-out red dress that showed just the right amount of skin and highlighted her lean physique.

The 31-year-old star visited Italy’s Eternal City for the premiere of Sofia Coppola’s debut opera, La Traviata, alongside her husband James Righton, and wore a scarlet Valentino gown that would befit a Grecian goddess. She kept the look simple with minimal jewelry and a classic half-up twist in her hair, letting the red-hot dress take center stage.

The Imitation Game starlet posed with her husband and designers Maria Grazia Chiuri and Pierpaolo Piccioli at the Teatro dell’Opera di Roma before watching Coppola’s take on Giuseppe Verdi’s classic opera.

Of course, this isn’t Knightley’s first red carpet rodeo. Here are ten more times the Pirates of the Caribbean star was a pro.
