Gigi, Bella, and their parents Mohamed and Yolanda Hadid head to a party in New York

Gigi looked gorgeous in a satin pink corset, and a long red skirt with sequins at the bottom, and a sexy slit. She wore a mask with a large white feather, pearl necklaces, and white opera gloves.

Bella was happy to pose for photos and headed into the party holding hands with her boyfriend Marc Kalman. She did not wear a mask but still looked true to theme.

The patriarch of the family, turned up with a mystery woman on his arm shortly after Gigi and Yolanda arrived. Mohamed looked true to the theme with a mask resembling the Phantom of the Opera.

Their mother Yolanda, who made headlines after an alleged scuffle with Gigi’s ex-boyfriend Zayn Malik, was all smiles in a simple black dress and lace mask. While they weren’t the exact same mask, it did resemble Mohamed’s mystery dates.
