January Jones joined Jon Hamm on the red carpet for the premiere of ‘Mad Men’ Season 5 at the ArcLight Cinemas in Hollywood, California, last night.

My first reaction to January in this Roland Mouret dress was, ‘What happened to her red carpet mojo?’

I don’t blame the look; it’s January who fails to breathe any life into it.

Imagine this look on Amber Heard or even Carey Mulligan, then look at Karlie Kloss, then come back to January.

Lifeless.

Even with the cute retro curls and the glossy lips, she’s not selling this look to me.

Cartier earrings completed her look.
