Like Charli D’Amelio, Olympic gymnast Sunisa Lee and her sister Shyenne Lee were inspired by the movie “Black Swan” for their costumes.

YouTuber Meghan Camarena paid tribute to the “Encanto” character Bruno, whose identity is unfolded in the jam “We Don’t Talk About Bruno.”

The costume also came with Bruno’s signature pet rat.

Kelsea Ballerini and Chase Stokes were a hot duo. The couple arrived at Klum’s extravaganza dressed as iconic lovebirds Sandy Olsson and Danny Zuko from “Grease.” The characters were played by John Travolta and the late Olivia Newton-John.

The two seemed to get into character on the red carpet. Stokes threw his arms around Ballerini with a cigarette dangling in his mouth – peak Danny Zuko.

Ahead of the party, Ballerini shared a sneak peek of her flirty look with the caption, “Happy Halloween, studs.”

Ballerini previously told Teen Vogue that she and Stokes originally planned to dress up as Moo Deng the pygmy hippo and Pesto the penguin.

“I felt good at Pesto, but I had a feeling it would be very sweaty and humid,” Ballerini said. Instead, they opted for a simpler costume to just have fun.

“(Chase and I are) both in such a full sprint right now. We walk in these parallels,” she told the magazine. “Let’s just dress up and have so much fun for an evening and be out of work mode a little bit.”

Charli D’Amelio, one of the most followed TikTokers on the platform, appeared dressed as Natalie Portman’s character in the 2010 film “Black Swan.”

The dance pairing is fitting: D’Amelio made her Broadway debut earlier this week in a dance-heavy ensemble role in “& Juliet.”

…an insect?

Leni Klum, Heidi Klum’s daughter, sported antennae and large black spots that made her eyes look like those of a fly.

In short, she made a fly seem to fly.

Leni and Heidi Klum, plus Kaulitz, stood for a family photo — even though they were all unrecognizable.

Heidi Klum promised it and she delivered.

She came to her party dressed as ET, the main character in Steven Spielberg’s 1982 film “ET the Extra-Terrestrial.”

Her costume is inspired by the scene where ET dresses in human clothing, lipstick and all.

Her husband, Tom Kaulitz, joined in the fun. He was also ET, but at a different point in the film.

Their costumes were given similar structures. Klum and Kaulitz’s eyes protruded from the necks of the costumes. The aliens’ heads looked like elaborate hats.

Last year, Klum was a peacock and Kaulitz was a giant egg.

Journalist Tamsen Fadal is the author of a book about menopause – and she’s taking her plea to Heidi Klum’s Halloween party.

She was having a “hot flash,” a common symptom of perimenopause. She wore an all-red outfit, including a wig, and a dress with the words ‘hot flash’. Her fan said: ‘Coming in hot.’

According to Johns Hopkins Medicine, 80% of women experience hot flashes during perimenopause.

Questlove, together with Gottmik & Violet, are among the DJs of the evening.

For his third Heidi Klum Halloween party in a row, Questlove came dressed as the Mad Hatter.

YouTuber Joey Graceffa may have read “The Lion, the Witch and the Wardrobe” as a kid… or maybe he just likes fauns.

Anyway, he showed up at Klum’s Halloween party as Mr. Tumnas, the friendly guide to Narnia, complete with his umbrella and scarf. The only thing missing is snow (and maybe some Turkish delight).

Bethenny Frankel posted prep videos of her blue contacts. Now we have the finished product.

Frankel dressed up as the DC Comics character Superwoman, wearing red, white and blue and a headband fit for an Amazon.

What came first: the costume or the egg?

Contortionist and “AGT” alum Sofie Dossi arrived with influencer Zach Justice in a transforming costume. Dossi was wrapped in an egg and then came out as a chicken. Justice was dressed as Colonel Sanders.

Watch out, chicken!

Klum live-streamed her “getting ready with me” process on Amazon. Below you will find photos of her transformation. She is swaddled in a costume, but what is it?

“I don’t tell anyone. I like the surprising part of it all,” she said.

Bethenny Frankel posted a behind-the-scenes video ahead of the party.

For her look, she wore colored contact lenses that turned her brown eyes into a mix of green, blue and hazel.

“I look like a Siberian husky,” she declared, looking at herself.

Singer Angelina Jordan channeled “Squid Game” for her Halloween costume, which was shared on Klum’s Instagram Story.

She is dressed as a contestant and is accompanied by one of the show’s deadly security guards.
