January Jones -- or shall we say Betty Draper -- turns 36 years old today, January 5th. The Mad Men star and mother of one is celebrating her birthday, so we're celebrating her!

We've taken a look back at January's style since she hit the Hollywood scene, and while she's taken a few risks (hello pompadour hair at the 2013 Screen Actor's Guild Awards) she definitely has style. Dressing chic even while dressed down, we're consistently impressed. Plus, she's one of those stars who feel like they don't need a stylist, but go it alone -- major kudos!
