Jennifer Garner was back on the red carpet last night for the first time since the birth of her second daughter Seraphina in January.

For the past few months Jen has been spotted running errands and shuttling big sister Violet, 3, back and forth to preschool, but the busy mom traded in her jeans and Ts for a decidedly more glamorous look at the premiere of her new film, Ghosts of Girlfriends Past.

Dressed in a black floor-length gown with her hair loose, Jennifer definitely didn’t look the part of the exhausted mom, though she recently revealed that with two young kids in the house she’s “certainly not sleeping”.

Jen’s co-star Matthew McConaughey says he enjoyed working with her on the film: “She doesn’t bring any riff-raff, frizzle-frazzle, extra-BS drama from the outside.” He has a way with words, doesn’t he?

What do you think of Jennifer’s post-baby premiere style?
