Once the 2026 Met Gala ended, a wave of after-parties across New York City brought a second round of standout style.

A-listers headed out Monday night, with many changing into bolder, more revealing looks.

This year’s theme, “Costume Art,” and dress code, “Fashion is Art,” set the tone inside — but outside, across nearly a dozen after-parties citywide, the rules quickly unraveled.

Stars including Katy Perry, Hailey Bieber and Margot Robbie traded elaborate couture for stripped-down statements that dominated the night’s second act.

Perry made a dramatic entrance at the Metropolitan Museum of Art on Monday night, stepping onto the red carpet in a futuristic face mask and a striking white dress.

Hours later, the aesthetic softened. Perry traded the edgy look for a more playful after-party moment, stepping out in a fitted pale pink dress with a fluffy, textured hem.

Bieber and Kendall Jenner turned heads walking side by side – Justin Bieber’s wife leaned into a sculpted, romantic aesthetic in a short white dress with a structured, corset-like bodice and an asymmetrical neckline. She paired it with minimal white strappy heels.

After making a statement on the Met Gala carpet, Jenner carried that same high-fashion intensity into the after-parties.

Jenner appeared to ditch part of her red carpet look and kept the nude-toned, form-fitting base resembling a sculpted bodysuit, accompanied by a sheer, silky skirt. The “Kardashians” star wore a sheer veil cascading over her head and face, adding a mysterious, ethereal finish with minimal accessories — a small pouch bag and simple heels.

Robbie struck a balance between casual and glam, rocking a white top and a shimmering multicolored jacket. She completed her look with a bold red clutch.

Lena Dunham embraced full drama on the Met Gala carpet before pivoting to something far more understated after dark.

Later in the evening, the “Girls” creator took a softer turn, floating through the after-parties in a voluminous white dress with loose layers.
