You can own a piece of Playboy history!
Hugh Hefner's new bride Crystal Harris is auctioning the wedding dress she wore in their New Year's Eve nuptials ... for a good cause.
The former Playboy Playmate of the Month is putting the gown up on Charitybuzz.com. The starting bid for the soft pink strapless Ramona Kaveza mermaid gown is $7,500. Also thrown in are the pair of encrusted Aruna Seth shoes Crystal wore.
A rep for Crystal tells toofab exclusively: "Crystal is donating this dress in memory of her good friend, Mary O'Connor. Mary was Hugh Hefner's longtime assistant of 40 years, and is credited with helping Crystal reconcile with Hef last year, ultimately leading to their recent wedding. Money raised will benefit the Leukemia and Lymphoma Society in Mary's name."
As toofab previously reported, Mary passed away Sunday.
That same day Crystal tweeted: "Hef's long time secretary & my dear friend Mary O'Connor has passed away. It's a very sad day here at the Playboy Mansion. We love you Mary."
