Keira fits into a 23-and-a-half-inch corset!

Washington (ANI): Keira Knightley's look-alike turned out to be her perfect body-double after she managed to fit into the actress' 23-and-a-half-inch corset. Justine Gale, who was used as the star's body-double, has revealed the entire experience of playing the character. "From sharing a tent with hundreds of extras, I now had my own trailer - complete with a bathroom, which was half the size of the huge dress I was wearing, creating all sorts of interesting challenges," FoxNews quoted her, as saying.

The first thing that struck me was the attention to detail. When required to play drunk, I had to study Keira's interpretation of Georgiana's swagger in order to produce the same movement for continuity purposes. "My skin and hands were whitened where necessary to get a perfect match - and I waved goodbye to my L.A. tan.

"When pulling in my corset, all measurements were checked ... I was most thankful for that on the day a new wardrobe assistant mistakenly pulled me into a 22-and-a-half-inch waist. Ouch! I'm sure Keira felt the same - and thankfully I was "let out" an inch," In the film, Knightley is playing the role of Georgiana, Duchess of Devonshire, who was the great-great-great-great aunt of Princess Diana.
