Newton-John's skin-tight Grease trousers up for auction

The skin-tight trousers and jacket worn by Olivia Newton-John in the finale of Grease are to go under the hammer.

In the scene, Newton-John's character Sandy dances to You're The One That I Want at a funfair with Danny Zuko, played by John Travolta.

The couple are finally back together following the classic will they/won't they storyline.

The jacket and trousers - which the actress had to be sewn into - are among more than 200 costumes, gowns, accessories and personal items owned and used by her to be auctioned for the Olivia Newton-John Cancer Wellness and Research Centre.

Newton-John, 70, revealed earlier this year that she had been diagnosed with cancer for the third time.

The items are expected to fetch between $100,000 and $200,000 (£79,000 and £158,000).

Other items that Grease lovers may want to get their hands on include Newton-John's original script from the film, and a custom Pink Ladies jacket presented to her by the cast and crew.

There is also a the 1950s-inspired pink lace gown she wore to the movie's premiere in Los Angeles.

From the film Xanadu, there will be some custom-made cream thigh-high suede western boots.

Martin Nolan, executive director of Julien's Auctions, described Newton-John as a "pop culture phenomenon".

He added that her "extraordinary career - that includes her starring role in Grease, one of the most successful Hollywood films and soundtracks of all time - and her recordings of some of the biggest pop singles of the 20th century make her more than just a star."

Before the auction on 1 and 2 November, the items will be on display at The Museum of Style Icons in Newbridge, Ireland, and The Standard Oil building in Los Angeles.
