On Tuesday night, inside Heidi Klum’s Halloween party at the nightclub Marquee in the Chelsea neighborhood of Manhattan, guests mixed, mingled and, in an attempt to converse over the din of the thumping music, pressed their faces together and shouted into each other’s ears.

Earlier in the evening, Ms. Klum revealed her highly anticipated costume: a giant human peacock constructed with the help of 10 Cirque du Soleil acrobats.

In a booth upstairs, the rapper Ice-T sat with his wife, Coco Austin, who was clad in fishnets. As she leaned over the back of the booth and chatted with some other guests, Ice-T snapped pictures of her. She did not appear to notice.

The club, filled with about 500 guests, was decorated for the holiday, with fun house mirrors lining the entryway and cobwebs draped from the ceiling. Across the room, the costumes were elaborate.

The singer Camila Cabello wore a short, white strapless dress and black headphones à la Princess Mia in “The Princess Diaries.” Leni Klum, Ms. Klum’s daughter, wore a frilly pink bra and underwear paired with a neon pink wig and green-and-white-striped thigh-high stockings.

Earlier in the night, she carried around a plastic container of fresh strawberries, another nod to her look’s inspiration, the children’s cartoon Strawberry Shortcake. “I ate them all,” she said.
