Rumer Willis wants to design a lingerie line.

The 27-year-old singer and actress - whose parents are Demi Moore and Bruce Willis - revealed she would love to create her own brand of underwear and sleepwear, along with bedding.

She said: ''I'm obsessed with lingerie and pjs. I'd love to do a store that I curate that has pretty much all of my favourite things: blankets, bed sheets, pillows, all of that. I love being comfortable - I have a collection of like 20 onesies. My friends joke around with me because I'm known for, like, my pillows, my mattress and my sheets.''

Rumer also revealed her fashion choices are influenced by her hairstyle, admitting she opts for an edgier style when her hair is shorter, as it is now, and chooses a more girly look when she has long locks.

She told the New York Post: ''What I wear depends on my haircut. I don't even notice it, but if I have longer hair I definitely dress more girly.

''Recently, I've really been into suits. I love the Kooples, and I'm really digging that whole androgynous, woman-in-a-suit thing. I'm always looking for something different, not necessarily what's trendy. I'm the most feminine tomboy you've ever met.''

Rumer previously revealed she decided to cut her hair because it was in bad condition after years of dyeing it.

She explained: ''I've been dyeing my hair a lot and it's been kind of getting trashed at the ends ... I just got to a point where I just wanted to cut it all off, kind of start fresh. I think with women, we put so much of our emotional stuff in our hair, and I think sometimes you just want to kind of chop it off and start over.''
