January Jones' red carpet style is the polar opposite of her Mad Men alter ego Betty Draper.

The actress rarely gets it wrong on the red carpet, opting for bold yet flattering dresses by designers like Versace, Elie Saab and Dolce & Gabbana. In honor of Jones' 34th birthday, Us Weekly has compiled her 15 most memorable looks over the years.

Though she often wears fashion-forward, risque ensembles, Jones still appreciates her '60s Mad Men wardrobe.

"The long-line bra with the pointy tips and the girdle and then the stocking on the garter belt, I really like the shape it gives me," she told Allure in 2011. "It's kind of sad when you take the girdle off at the end of the day."
