Two collectors paid over $400,000 at a recent auction for some very special items from the original film, Grease.

Olivia Newton-John’s iconic Grease leather jacket and skintight pants were the big-ticket items on Saturday in Beverly Hills. Julien’s Auctions says the combined ensemble, which the actress’s character, Sandy, wore in the closing number of the 1978 film, fetched $405,700 total. The top officially sold for $243,200 and the pants, which Newton-John famously had to be sewn into, went for $162,500.

In addition to the main attractions, other Grease memorabilia included a Pink Ladies jacket that went for $50,000 and a poster signed by Newton-John, John Travolta, director Randal Kleiser and producer/songwriter John Farrar sold for $64,000. The event was done for a good cause as the proceeds from the jacket and pants, as well as a portion of the other items sold, will go to the Olivia Newton-John Cancer Wellness & Research Centre in Australia.

Grease was a critical and commercial success becoming the highest-grossing musical film ever at the time. Its soundtrack album ended 1978 as the second-best selling full length of the year in the United States, behind the soundtrack of the 1977 blockbuster Saturday Night Fever (which also starred Travolta).
