Last night, the artist Marina Abramovic concluded her 68-day performance piece “The Artist is Present,” at New York City’s Museum of Modern Art, and Givenchy hosted a star-studded dinner to celebrate the close of her exhibit. Most of the celebrities—including Liv Tyler, Christina Ricci, Courtney Love and Ciara—donned current-season dresses designed by the label’s creative director, Ricardo Tisci, and the prevailing fashion mood was accordingly darkly conceptual, even goth. (Bjork, always the individualist, broke ranks by opting for an ornate gold mini-dress from the archives.) Click on the gallery to see the looks, or visit MOMA’s Flickr feed to see photographs of stars like James Franco, Isabella Rossellini, Marisa Tomei, Sharon Stone, Kim Cattrall and (again) Bjork taking part in the now-closed performance.
