Sydney Sweeney keeps a spare wig in her Miu Miu bag. Don't you?

Everyone loves Jane Birkin bags, including Sydney Sweeney. The actor adorned her sturdy black Miu Miu Aventure handbag with a charm dedicated to her pup and dog cover girl tank. “She means everything to me. I love her,” Sweeney said. Even her Laneige vanilla lip balm has a charm: a yellow star and a tiny ice cream cone. “They made it for me and I’m obsessed with it,” the star said.

The actor’s wallet is filled with unused gift cards from his 18th birthday — from BJ’s (“because I like pizookies”), Michaels and gas stations. “When I turned 18 I thought I’d have to save this in case I went bankrupt one day,” he said.

As Swinney knows, no purse is complete without snacks, and given her nonstop schedule, she needs to be ready to eat on the go. (Who cares if these snacks have nutritional value?) “I’m a candy girl. I always need candy to fuel me up,” she says. “I always have some candy in my purse.” Today’s choice? A bag of Black Forest gummy bears.

Although many viewers may recognize the contents of Swinney’s purse from her own, they are unlikely to see the “Flawless” star’s bloodied face. She jokes that one of its uses is to combat road rage in Los Angeles. “If I’m driving and somebody honks the horn at me, I turn around,” she said, lifting the mask to her face. Many of her outfits are not like that. “Doesn’t everyone carry a wig in their purse?” she said, tossing a curly brown mop on her head.
