Marnie would be scandalized!

Though Allison Williams’ personal style seems to match her Girls alter ego -- “When it comes to my style icons, I’ve always had a thing for the K’s: Keaton. Kelly. Kruger. Kate. Katharine,” she writes of her “rustic preppy (if that’s a thing)” aesthetic in harper by Harper’s BAZAAR magazine -- the photoshoot would certainly make the perpetually prudish Marnie blush.

Like this shot of the actress posing topless in a pair of metallic pants.

It’s the photo of Williams showing off her insane abs that had us practically knocking each other over to learn her workout secret. “This is my gift to you: Spanx makes the most incredible exercise spandex,” Williams reveals as guest editor of the magazine.

“I wear them almost every day,” she adds. “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.”

As for any dieting tips? Take out.

“I am the world’s worst cook,” she reveals. “Not only am I bad at it, but I also have some kind of inability to learn…I’m perpetually worried that the meat is going to poison everyone, so it ends up being black. It’s a nightmare, so I just order in.”
