In 2018, at a fitting ahead of the fashion show, the supermodel Bella Hadid was being measured for underwear that would meet broadcast standards. Mr. Razek sat on a couch, watching.

“Forget the panties,” he declared, according to three people who were there and a fourth who was told about it. The bigger question, he said, was whether the TV network would let Ms. Hadid walk “down the runway with those perfect titties.” (One witness remembered Mr. Razek using the word “breasts,” not “titties.”)

At the same fitting, Mr. Razek placed his hand on another model’s underwear-clad crotch, three people said.

An employee complained to the human resources department about Mr. Razek’s behavior, according to three people. The employee presented H.R. with a document last summer listing more than a dozen allegations about Mr. Razek, including his demeaning comments and inappropriate touching of women, according to a copy of the document reviewed by The Times.

It wasn’t the first H.R. complaint about him.

At a photo shoot in June 2015, the company put out a buffet lunch for staff. Ms. Crowe Taylor, the public relations employee, went to get seconds. Mr. Razek intercepted her, she said. He blocked her path and looked her up and down. Then, with dozens of people watching and Ms. Crowe Taylor holding her empty plate, he tore into her, berating her about her weight and telling her to lay off the pasta and bread.

Ms. Crowe Taylor, who was 5-foot-10 and 140 pounds, fled to a bathroom and burst into tears. She said that she had complained to H.R. but that as far as she could tell, nothing happened. She quit weeks later.

In October, shortly after Mr. Razek had left the company, Monica Mitro, a top public-relations executive at Victoria’s Secret, lodged a harassment complaint against him with a former member of the L Brands board of directors, according to five people familiar with the matter. She told colleagues that she had gone to the former director because she didn’t trust the H.R. department.
