Lily James Wore a 'Boob Flattener' for 'Downton Abbey'

Lily James is gorgeous in white while stepping out for an AOL Build Session on Wednesday (January 27) in New York City.

That same day, the 26-year-old Pride and Prejudice and Zombies star stopped by IMDb Asks for an interview with Jerry O’Connell about the film.

Lily also opened up about working on Downton Abbey.

“At times I wore a sports bra and a boob flattener, because at that time the style was, in the twenties, to actually emulate a man’s physique,” Lily said. “There was the low-cut drop waistline in this sort of very square shape so the women would flatten their boobs to fit into the style. Women were becoming liberated and doing the flapper and dancing and showing that they were sort of equal.”
