Another fall, another ballet. On Thursday, the New York City Ballet will host the world premiere of three new ballets – the costumes of which will be designed by three important designers. Theory’s Artistic Director Olivier Theyskens will design the costumes for a ballet by Angelin Preljocaj; the well-known Nepalese designer Prabal Gurung will collaborate with choreographer Justin Peck; and the Dutch designer Iris Van Herpen will work with Benjamin Millipied. NYCB has a history of collaborating with fashion designers. Last year, Valentino Garavani designed ruby-red costumes for George Balanchine’s Rubies – which culminated in a spectacular homage to the color red. But this season’s selections are said to aim to attract younger audiences to the Ballet. The fall season will kick off on Thursday night with the Ballet’s annual fall gala, co-chaired by Sarah Jessica Parker.
