The bold and the beautiful turned out for cancer-fighting charity DKMS in New York last night, with attendees including Rihanna, Keri Hilson, Leighton Meester, Iman, Solange and Eva Mendes among the guests. We particularly liked Keri Hilson’s outfit, in part because it oh-so-nicely showcases her rack but also because it features a cut-out detail, one of our fave Spring 2011 dress trends.

A few more celebrity images from the TriBeCa Film Festival taking place now in New York City. Chloe Sevigny is featured above, bedecked in a lace dress with a black bag and heels. On the next page images of Rachel Roy and Nina Garcia, both looking fab and happy, plus Julia Roitfeld, Hayden Panettiere, Lorenzo Martone and Eva Mendes, wearing a very red dress.
