Jon Hamm turns 43 today! Happy birthday, Jon Hamm. Chiseled of jaw, and often big in the beard, we've been digging Hamm's work for some time now. 

He was awesome in bank robbery flick The Town, and killed it in Bridesmaids. Plus he's happy to lend his voice to cracking shows including ArcherRobot Chicken and The Simpsons.  

But it's his award-winning turn as shady ad man Don Draper in Mad Men that really cemented his place as a true style icon. Check out our favorite looks from Draper/Hamm's wardrobe:
