Tuesday night saw the unveiling of yet another round of art and fashion collaborations. At the Guggenheim, Louis Vuitton offered a peek at its new Richard Prince-designed accessories. The event coincided with the closing of the museum's Prince retrospective, and echoing some of the artist's paintings, the models showing off the handbags wore nurse uniforms. "I'd wear a nurse's outfit for Richard any day," said guest Kelly Killoren-Bensimon. Meanwhile, at the Max Lang gallery, Repetto debuted its traveling exhibition of customized footwear for a crowd that included Phillip Lim, Charlotte Ronson, and Byrdie Bell. The 60th anniversary show featured shoes designed by artists both professional (Karen Kilimnik) and amateur (Jessica Stam). "I enjoy creating things with my hands," said the model. "But I wouldn't expect anyone else to like what I produce."
