Rumer Willis steals her mother Demi Moore's clothes to wear.
The 22-year-old star - who was recently announced as the face of Badgley Mischka, the new luxury clothing brand created by Mark Badgley and James Mischka - admires the actress' style and always raids her wardrobe for designer items.
But although she is happy to take her mother Demi's garments, Rumer hates it when her sisters Scout and Tallulah wear her clothes.
Speaking at the opening of Badgley Mischka's new flagship store in Rodeo Drive, Beverly Hills, she said: "I've definitely raided her closet quite a bit. But the problem is when my sisters raid my closet and my stuff disappears. But when it comes to fashion you should always trust your gut instinct."
Rumer - whose father is Hollywood action legend Bruce Willis - admits she has loved working with designers Mark and James on the advertising campaign for their label.
The 'Sorority Row' actress has been so inspired by their creations that she has been contemplating releasing her own clothing range in the future.
She told People: "Their stuff is elegant and glamorous, and I think every woman loves to have that feeling once in awhile.
"Watching two people so involved in the whole design process is inspiring. Especially if I, at some point, did something like this."
