Here's your chance to own a piece of Playboy history.
Crystal Hefner (née Harris), Hugh Hefner's new wife, is auctioning off the dress she wore when she married the Playboy founder last year. According to her rep, the money raised will be donated to the Leukemia and Lymphoma Society in honor of Hefner's longtime assistant, Mary O'Connor, who died on Sunday.
The pale pink strapless Ramona Kaveza mermaid gown can be found on Charitybuzz.com with an estimated value of $7,500. The encrusted Aruna Seth shoes Crystal wore will also be included with the dress. Here's a photo of the gown that Crystal tweeted on her wedding day:
Hefner credited O'Connor with helping him and Crystal reconcile after Crystal called off their wedding in 2011. In June 2012, Hefner tweeted, "It's Mary O'Conner [sic] that brought Crystal Harris back. Crystal was miserable & said so. Mary told Crystal to write & tell me, which she did."
The couple married on New Year's Eve 2012.
