The 30-year-old actress is the latest participant in Hammer's "Role Models Not Runway Models" campaign Hammer started when she was first asked to show her line at Fashion Week last year. The designer wanted to represent the women who bought her clothing, and featured real-life inspiring women such as her friend, Danielle Sheypuk, a doctor and a sex therapist who uses a wheelchair.
"Young girls and even young women … [see me] and say, 'Hey, if she can do it so can I,'" Jamie, who's also an advocate for people with intellectual disabilities, tells TODAY about the exciting new gig. "It's a true inspiration being a role model for any young women to [encourage them] in being who they are and showing who they are."
As for what she'll be wearing, Hammer says she chose a dress specifically with Jamie in mind. Jamie's played such fan favorite roles as Addie in American Horror Story: Murder House, Nan in Coven, and Marjorie in Freak Show.
"American Horror Story is dark, scary, bewitching so we had to go with black and Jamie has a beautiful body with a teeny waist and curves and we went with an A-line," she says.
And clearly, Jamie couldn't be happier with the end result.
"It's amazing, it's really neat," she says. "Many women have many sides to their personality, this dress fits ... mine. I am honored to be in it."
