The skin-tight black satin pants that Olivia Newton-John wore in the 1978 movie Grease were auctioned off last weeks at Julien’s, fetching $162,500. Now it’s been revealed that the winning bid went to Spanx founder Sara Blakely (above) who says she plans to frame them and hang them in her Atlanta headquarters, because they inspired the company’s black faux-leather leggings.

Blakely says she is huge Newton-John fan, while Newton-John says that she’s excited Blakley purchased them.

Julien’s Auctions also notes that the leather jacket that Newton-John’s character, Sandy, wore fetched $243,200, bringing the total for the outfit to $405,700.

The proceeds from the jacket and pants, as well as a portion of the other items sold, will go the Olivia Newton-John Cancer Wellness & Research Centre in Australia
