Supermodels and fashion world bigwigs hit the Top of the Standard this weekend to celebrate the 50th birthday of power modelling agent and IMG Vice President Luiz Mattos with a black tie masquerade bash for the ages.

The seriously chic soiree brought out Mattos's A-list friends and clients, including Gigi and Bella Hadid, Precious Lee, Meghan Roche, photog Ellen von Unwerth, and makeup artist Patrick Ta.

The Hadids, who were also joined by their parents Yolanda and Mohamed, went all out for the party, donning couture corsets and intricate masquerade masks. If there's one thing about the model sisters, it's that they certainly know how to dress for the occasion.

Complete with stunning 360 degree-views of the city, a mini orchestra, and a wall of roses spelling out the birthday boy's name, the affair was, as expected, beyond glamorous (and very Instagrammable).
