The fashion set stepped out last night for one of the most anticipated events of the spring gala season, New Yorkers for Children Tenth Annual Spring Dinner Dance. Models, socialites and all of our favorite A-listers were in attendance at the annual Fool's Fête, held at the Mandarin Oriental, to support youth in foster care. Not only did everyone, from Olivia Palermo to Lindsey Wixson, show off their philanthropic side, they also showed off some very colorful gowns, just in time for the gorgeous spring weather in NYC yesterday. Click through to see all of our favorite, festive looks from the evening.
