Besides foregoing the title of Mrs. Hugh Hefner, Crystal Harris is also leaving behind a pair of wedding shoes with an estimated price tag of $635!

The 'Aliah' ballerina flats by designer Aruna Seth have satin and Swarovski crystal accents -- the bride-to-be was planning to pair them with her Romona Keveza wedding gown so that she wouldn't tower over her 85-year-old fiance.

On Tuesday, Harris, 25, broke off her engagement to Hugh Hefner. The Playboy founder tweeted, "The wedding is off. Crystal has had a change of heart."

Harris's rep, Michael Blakey, told Us Weekly on Tuesday that he "spoke to Crystal earlier this morning and she had shared the sad news with me. The breakup was amicable. Crystal will now be focusing on her music career and her new single 'Club Queen,' which was released today."

Tuesday evening, Hefner took a small dig at his ex-fiancee: "The breakup is a heartbreaker, but better now than after the marriage," he somberly tweeted. "Since we're not getting married on Saturday, I've scheduled a movie: Runaway Bride. Seems appropriate."
