No doubt, Versace and H&M know how to throw a party. Last night at Pier 57 in NYC, celebrities and designers came out in droves to attend the Versace For H&M fashion runway show and the rockin' afterparty that followed with performances by Prince — who sang a song especially for Donatella along with classics like "Purple Rain" — and Nicki Minaj. The venue was transformed for the night with fancy Versace-inspired mirrors and a maze-like runway. The collection captured Dontella's signature bold style as models strutted down the runway in an array of party-perfect studded and sequin dresses along with '90s cool floral motifs. Off the runway was just as exciting; we spotted Uma Thurman and Jessica Alba along with Gossip Girl stars Blake Lively and Kaylee DeFer hugging it out in their gorgeous Versace ensembles. We almost had a geek-out moment when we had an up close and personal encounter with the dapper Chace Crawford. Want to see more?
