Lizzy Caplan has become attached to the underwear she wore whilst filiming new show, Masters of Sex.
The actress admitted that she loved the retro styling clothing for the show, which is set in the 1950s.
She even took home some of the shapewear she had to wear.
Lizzy - who stars alongside Michael Sheen in the new period drama which explores the work of sexual behaviour researchers Virginia Johnson and Dr. William Masters - enjoyed wearing her costume shapewear so much, she helped herself to some of the outfits.
She said: "I became very attached to the underwear and would take it home. I loved the girdle and the stockings. It really helps your posture and is so flattering. Women looked fantastic back then - until they took that girdle off, anyway."
Most of the retro designs worn by her character were designed just for Lizzy and the 31-year-old beauty was ecstatic to have her very own wardrobe.
She enthused to LOOK magazine: "Ane Crabtree, our wardrobe designer, is a genius. A huge percentage of the dresses she made specially for me."
No doubt Lizzy hopes her wardrobe will make her a style icon similar to curvaceous Christina Hendricks' Joan Holloway in hit 1960s-set period drama 'Mad Men'.
The show's costume designer, Janie Bryant, previously revealed how she styles flame-haired Christina in girdles and longline bras to achieve Joan's famous hourglass figure.
