Paulina Porizkova, a onetime supermodel and actress, is opening up about the pattern of sexual harassment she saw in the industry as a teenager.

The Czech-born model, 60, posted a video to Instagram Thursday, detailing several uncomfortable encounters she had at the start of her career, when she was 15 years old.

"Sometimes the people I was seeing were well-dressed and in offices, and sometimes they were middle-aged guys in messy apartments who just wanted to take a few casual photos of me – you know, preferably topless," she said of the "go-and-see" calls her modeling agency sent her on. "I've lost count of the amount of men in open bathrobes who greeted me in their hotel rooms or apartments where I have been sent by an agency or clients."

"I took it all for granted," Porizkova continued, "that my job was to take my clothes off, put my clothes back on and then learn how to creatively fend off horny men so that you don't offend them and lose a job."
