On Friday night, Manhattan royalty (and actual royalty) decked themselves out in flowers, feathers, and lace - and no, it had nothing to do with Coachella. Save Venice's annual Ballo in Maschera went down at The Plaza Hotel, and everyone who's anyone donned their most glamorous masquerade looks for the occasion.

Sponsored by Moda Operandi, Oscar de la Renta, and Bulgari, the event was certainly a stylish one, and we're not just talking about the looks donned by Lauren Santo Domingo, Nicky Hilton Rothschild, and Princess Maria-Olympia of Greece. The Plaza's ballroom was transformed into a Venetian playground by events firm Van Wyck & Van Wyck, featuring garlands of red roses and a glittering Venus de Milo. Combine that with all the over-the-top masks and headpieces, and you've definitely got a night to remember.
