Dakota Johnson took ''comfortable'' underwear from the 'Fifty Shades of Grey' set.

The 25-year-old actress had to wear sexy lingerie in the erotic film for her role as Anastasia Steele and has admitted that she even stole a couple of them.

She said: ''I stole lots of the underwear - they were comfortable.''

Dakota also admitted to stealing a flogger - which is made up of a handle and several straps - from the set but insists it is simply gathering dust in her garage.

In a Q&A with Glamour magazine, she said: ''I do have a flogger in my house (it's in the garage with dust).''

Whilst the star credited ''getting to meet everyone'' as the best part about appearing in the movie, she admitted it was a daunting prospect signing up for the film because she had to appear nude on screen.

When asked what her biggest sacrifice has been, she replied: ''To do Fifty Shades. The whole world can see me naked.''

Meanwhile, Dakota previously admitted that she still has ''moments'' where she wonders if she was right to take on the role in the film.

She said recently: ''Even now there are moments when I think, 'What the f**k have I done?' But most of the time I feel pretty solid about it.''
