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".
