January Jones Flashes Her Bra in a Sheer Top

January Jones looks gorgeous while posing for photos at Francesco Carrozzini‘s celebratory dinner held on Thursday (April 14) at a private residence in Beverly Hills, Calif.

The event was held to announce the photographer’s appointment as Creative Director for Peroni Nastro Azzurro’s ‘House of Peroni,’ coming this September to New York City. Also in attendance were Ben Barnes and Devon Aoki.

January wore a suit with a sheer top that showed off her bra.

Earlier that day, January took to Instagram to share a photo of her beauty regime. “Aging gracefully,” she captioned the photo.

FYI: January is wearing an Antonio Berardi top, jacket, and pants.
