As promised, Daphne Guinness performed an her art installation in the windows of Barneys yesterday. Behind a frosted glass screen, Daphne got dressed for the Metropolitan Costume Institute Gala in an Alexander McQueen creation - of course.

In front of hundreds of keen viewers and a helper, she got dressed in a cream feathered gown and sheer wrap which she subsequently uncovered from her face before proceeding with her performance art piece. The heiress then hit the red carpet at the Gala where she was very appropriately dressed.
