Jessica Simpson Can't Do Betty Draper

Jessica Simpson attempted her best Mad Men outfit while making an appearance on The Tonight Show Wednesday night and failed!

The dress she’s wearing isn’t doing her curvy figure any justice. She comes off as top heavy and the belt makes her body look disproportionate.

And judging by her hair, Ken Paves wasn’t able to accompany her on the trip.

What do U think of Jess’ look???
