And of course it delivered on all fronts; Harper's BAZAAR really pulled all the stops to ensure this was not just one of the best parties of fashion week, but one of the best events of the year. The event was outrageously glamorous, from the chic Plaza Hotel ballroom to the elegant, flowing dresses the sea of models dressed themselves in. Lady Gaga's jazz performance was the cherry on top of the unforgettable night.
