It was model- and fashion-crowd mania last night in NYC at the 9th annual Spring Dinner Dance to benefit youth in foster care. Coco Rocha and Crystal Renn made dramatic entrances in gowns designed by Zac Posen, Jessica White wore a berry-hued sequin wrap dress from Diane von Furstenberg, while Erin Heatherton opted for a more modern printed dress. Needless to say, we're inspired to amp up our evening looks with similar touches of color and drama.
