Harry Styles was one of the many stars who showed off an epic Halloween costume this year.
The musician dressed up as Dorothy from "The Wizard of Oz" on Saturday, while performing the first of his two "Harryween" shows at New York's Madison Square Garden.

The "Watermelon Sugar" singer's band also joined him, dressing up as the Cowardly Lion, the Glenda the Good Witch, the Tin Man, the Wicked Witch of the West, and various other characters from the 1939 film.
Lizzo also went all out for the holiday, donning several costumes over the weekend. She fully transformed into Baby Yoda from "The Mandalorian" for the first night of celebrations, the doll from "Squid Game" for her next costume and finally Dorothea from the 1992 animated comedy, "Bébé's Kids."
Ciara, who usually shows off several impressive looks for the holiday, channeled late icon Selena for her first costume and transformed into TLC for her second.
