Allison Williams covers the December/January issue of Harper’s Bazaar and goes topless inside the editorial.

The “Girls” star, who also helped to guest-edit the issue, posed in denim and leather pants for the casual shoot and opened up about her personal style, which is equally as laid-back.

When it comes to my style icons, I’ve always had a thing for the K’s: Keaton. Kelly. Kruger. Kate. Katharine. They all represent sophisticated fashion that’s also full of life. After all, clothes are fun — it’s dress-up for adults. I’d like to call my style easy, timeless, and rustic preppy (if that’s a thing), which most often translates as endless button-downs, a chic pair of boots, a good variety of sweaters, and my staple — jeans.

She also had a piece of advice when it comes to athletic-wear: Spanx.

“This is my gift to you: Spanx makes the most incredible exercise spandex,” she said. “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.”
