Jennifer Garner is one of the most relatable celebrities out there — from her hilarious Instagram to her errand-running ensembles. But the actress just traded in her usualy functional fashion for a sophisticated red carpet look and we can't get enough.

On Monday night, the actress attended the New York City premiere of her new movie, The Adam Project, in which she stars alongside Ryan Reynolds, Zoe Saldaña, and Mark Ruffalo. For the occasion, Garner wore a sexy black halter gown with a high neckline trimmed with white fabric. The tapered dress also featured a high slit up the middle, which showed off her toned legs and bejeweled pointy-toed pumps.
