Blow. Guinness. Gaga. These three eccentric icons of fashion are now forever linked thanks to Daphne Guinness' fashion auction at Christie's, which raised almost $742,000 for the Isabella Blow Foundation -- more than quadrupling her expectations and setting a few world records in the process.

"As I watched the auction from invisible wings this evening, I crossed my fingers and toes," said Guinness, who expected to raise around $150,000 to benefit the charity she established in honor of her late friend, editor/muse Isabella Blow.

The star lot of the night was the above portrait, "Daphne Guinness," by Mario Testino that appeared in British Vogue in 2008, fetching around $207,000 and setting a world record for a Testino piece.

Another record was set, rather appropriately, for an Alexander McQueen piece. Blow is credited for discovering McQueen and both she and Guinness were close friends of the designer. An empire-waist gown that the heiress wore in UK Harper's Bazaar earlier this year brought in around $128,000 -- exceeding the estimated $23,000 - $30,000.

A white lace Christian Lacroix dress with a black matador jacket set the last record for the night, drumming up some $25,000 from a private bidder in the U.S. -- who may or may not have been Lady Gaga. The popstar contributed to the success of the auction, though what she bought remains a mystery.

"I'm particularly moved by Lady Gaga's support for the Foundation," Guinness told the Telegraph. "I like her very much, and it's lovely to see the nascent beginnings of something that may help other people."

Not every piece sold for thousands as a Narciso Rodriguez gown and another Lacroix went for relative pocket change at $194 and $370, respectively. However Guinness, for her part, was still "overwhelmed" by the response to the auction. [Telegraph]
