When the Cruz sisters throw a party, you better believe it's going to be filled with fashionable A-listers. In celebration of the newly renovated Mango flagship in SoHo, Monica Cruz hosted a fete filled with beautiful clothes and lovely party-goers. Solange Knowles performed for giddy guests Marc Jacobs, Dakota Johnson Griffith, and Ashley Olsen, to name a few. You can tell from the pictures — check out Genevieve Jones and Julia Restoin-Roitfeld in a chummy hug — everyone had a blast. Looks like some of the party animals should have remembered to pack their morning-after clothes.
