| The outfit that marked the singer's transition 
				from demure high schooler to sexy Sandy Olson for the "You're 
				the One That I Want" duet with John Travolta in the 1978 movie 
				musical is expected to fetch up to $200,000, Julien's Auctions 
				said.
 "The pants have a broken zip and I had to be stitched into them 
				because they were made in the '50s," Newton-John, 71, told 
				Reuters Television ahead of the sale.
 
 The British-born, Australian-raised actress, who is battling 
				breast cancer for a third time, is selling more than 500 items. 
				They include her original script from the film, estimated at up 
				to $4,000, the pink gown she wore to the "Grease" premiere in 
				Los Angeles, estimated at $3,000-$5,000, and a custom Pink 
				Ladies jacket given to her by the "Grease" cast and crew.
 
 Although it took a long time to sort through her career 
				memorabilia for the auction, making the decision to sell was 
				easy.
 
 "I've realized over the years, especially when you go through 
				stuff, that stuff isn't what's important," she said.
 
 "It took quite a few months to weed through boxes and storage 
				containers. But it was a fun venture. It just took a lot of time 
				and sorting and it started out really that I was just going to 
				auction off the 'Grease’ jacket and pants for my cancer wellness 
				center in Australia. And then it kind of grew out of that,” she 
				said.
 
 Newton-John said earlier this year that she was battling breast 
				cancer for a third time since after first being diagnosed in 
				1992.
 
 She helped set up the Olivia Newton-John Cancer Wellness and 
				Research Centre in Melbourne, Australia, which aims to support 
				the mind as well as the body.
 
 The auction will take place at Julien's Auctions in Beverly 
				Hills on Saturday and a portion of the proceeds will go to the 
				Wellness and Research Centre.
