Jennifer Lopez donned a black, strapless mini-dress from Marc Jacobs’ Spring/Summer 2009 ready-to-wear collection for Louis Vuitton to attend a book party for her makeup artist, Scott Barnes, in New York on Wednesday night.

She wore the dress with a pair of Satin d’Orsay Années Folles heels from the Christian Louboutin Spring 2010 collection, and finished her look with a small, black clutch.
