Jumpsuits can be a tricky look to pull off, but we must say -- Jennifer Garner nailed this one at the Fifth Annual Thirst Gala, which she hosted this week in Beverly Hills. Ben Affleck's gorgeous wife sported a sleek and chic, black keyhole number on the red carpet. The look was cool and casual, yet still sophisticated.

It takes one brave woman to work a jumpsuit, but mom of three Jennifer proves it's not too hard. Black is instantly slimming, and the keyhole neckline adds a little sex appeal to the monochrome ensemble. Jennifer accessorized with just the basics, which we think was a good idea -- let the jumpsuit work for you by acting as a statement piece. Heels are also key, elevating your look and maintaining that sleek effect. A pop of bright nail polish doesn't hurt either.

Stealing Jen's look is pretty simple -- just find a black jumpsuit tailored to your style and budget. To start you off, we've chosen a few of our own that emulate Jen's sophisticated vibe. Click through the gallery to see them all.
