While Hilton and her little ones may have trick-or-treated as Spears and the cast of Winnie the Pooh, the family of four previously participated in a very colorful Halloween photoshoot with two epic family costumes.

Sharing several photos of the family's looks on Instagram, Hilton channeled Glinda the Good Witch from The Wizard of Oz, wearing her iconic pink dress, silver crown and carrying a wand. Reum dressed as the Wizard while London went as Dorothy, and Phoenix dressed as Munchkin, wearing a plaid shirt and red pants.

The crew was also photographed in a Rainbow Brite-inspired costume, with Hilton wearing a latex rainbow jumpsuit like the titular character. She carried Phoenix, who went as a unicorn, while Reum dressed as Murky, holding London.

Attending the 2024 CFDA Fashion Awards on Monday, Oct. 28 at the American Museum of Natural History in New York City, Hilton chatted with PEOPLE about the upcoming reboot of her show The Simple Life.

Speaking about which items from her time on the show that she still has in her own closet, Hilton says she's saved a lot of them for her daughter. "I keep a lot of those pieces because they're very iconic," she told PEOPLE.

"Some I'm going to give to my daughter London," Hilton said. "Probably not the low-waist cut jeans or the miniskirts, but she will get the Dior and the Louis."
