Allison Williams isn’t about to let being a married woman stop her from showing off some skin.

The normally demure “Girls” star posed topless for the latest issue of harper by Harper’s Bazaar, Bazaar’s contemporary supplement for young women, which she also guest-edited.

Williams, the daughter of disgraced newsman Brian Williams, also offered up an unexpected fashion tip in the magazine.

“This is my gift to you: Spanx makes the most incredible exercise spandex,” she said of the brand, known for its slimming garments. “I wear them almost every day.  They have a little control top, so they’re flattering.  I’ll often stay in exercise clothes all day, which I know is a faux pas.”

The actress married longtime boyfriend Ricky Van Veen in a star-studded yet private wedding in Wyoming in September.
