January Jones In Zuhair Murad  - The Tonight Show Starring Jimmy Fallon

January Jones made a guest appearance on ‘The Tonight Show Starring Jimmy Fallon’ on Friday (March 28) where she was promoting the last season of ‘Mad Men’, but she also shared a prank which she played on her ex-boyfriend from 20 years ago.

Opting to go sexy, and possibly commando, the actress wore a Zuhair Murad Fall 2014 sleeveless black silk jumpsuit featuring sheer embroidered panels inset along the leg and bodice.

Even with the revealing panels, the look didn’t come off as trashy or try hard.

Do you agree?
