January Jones 'Mad Men' Premiere Dress: Yay Or Nay? (PHOTOS, POLL)

January Jones is settling into her comfortable role as Betty Draper, turning up at the "Mad Men" season five premiere (we're so excited, by the way) to fete the new season alongside Jon Hamm, Alison Brie and other cast members.

Jones, a new mom and a blogger for The Huffington Post, slipped into a Roland Mouret black cutout dress that was flounced up with a white ruffle at the hem.

We dig her retro bob and glossed lips (very, uh, "Mad Men"), but still, we're not sure what to think about the dress. It reminds us of something Rooney Mara would wear, but we're not sure Jones has the same kind of cold Scandinavian charm (or something?) to pull it off.

But that's just our two cents... what do you think? Check out her frock and vote below.
