Halloween promises fun with trick-or-treating, decorations and being scared out of your mind at haunted houses. However, there is an additional aspect that can be both impressive and controversial, and that is what celebrities wear for this beloved holiday. For his concert at the Kia Forum in Los Angeles, Harry Styles transformed in Danny Zuko from famed musical and movie Grease. He also performed a rendition of “Hopelessly Devoted to You” from the same production. Kendall Jenner poked fun at a viral moment of her awkwardly slicing a cucumber during an episode of “Keeping Up with the Kardashians” by dressing up as a giant cucumber slice, complete with a fake knife.

Heidi Klum, who is no stranger to wearing the most eccentric and well-executed Halloween costumes, celebrated her first Halloween party in two years by dressing up as an enormous worm while her husband was dressed as a fisherman with a bloody eye. Klum’s costume had a wide array of reactions, but it was undeniably original. At the opening of Starchild Rooftop Bar & Lounge at CIVILIAN Hotel in New York City, musician Anderson Paak was dressed as a nun. Celebrity couple Justin Timberlake and Jessica Biel dressed as Harry and Marv, also known as the Wet Bandits, from the “Home Alone” movies.

There were a variety of costumes that, much like Klum’s, you would have had no idea who they were without explanation. For example, actor Sam Richardson sported a head-to-toe ensemble of Skeletor from the “Masters of the Universe” franchise. Machine Gun Kelly and Megan Fox complemented each other’s costumes, dressing up as Link and Zelda from the “Legend of Zelda” franchise. However, their other religion-themed couple’s costume earned them a fair bit of backlash.

Jaden Smith, the son of Will and Jada Pinkett Smith, dressed up as Harry Potter, complete with Gryffindor robes and the famous round glasses. Rapper Cardi B took her costume to the next level and painted her entire body yellow to dress as Marge Simpson, as did Lizzo. Lil Nas X was one of many celebrities that had more than one costume for the occasion. For one party, he dressed in a devil-like ensemble that appears similar to what is seen in his music video for “MONTERO (Call Me By Your Name).” For another party, the rapper dressed in a robot/alien-like costume.

For the premiere of The Jennifer Hudson Show, the titular host dressed up as Whoopi Goldberg’s character, Sister Mary Clarence, from “Sister Act.” One particularly amusing costume was worn by Joe Jonas who dressed as Flo, the famous Progressive insurance spokesperson. Among the great Halloween costumes included those that were done in pairs or groups. One such example was singer Ciara and her daughter, who dressed as Serena and Venus Williams from their Got Milk? campaign.

Billie Eilish and Jesse Rutherford were criticized for a costume calling attention to their eleven-year age gap, dressing as a baby and a grandpa. “Riverdale” alumni Lili Reinhart, Madelaine Petsch and Camila Mendes appeared as a trio for the third year in a row, all dressed as the Sanderson sisters from “Hocus Pocus.” Of course, as they do every year, Neil Patrick Harris and his family won Halloween. Harris, his husband and their two children each dressed as fast-food mascots, with Harris as Ronald McDonald, husband David Burtka as the Burger King and twins Gideon and Harper as Colonel Sanders and Wendy, respectively. Although Halloween has sadly departed us, we can continue to fondly remember each of the costumes we were able to enjoy thanks to our celebrities.
