Millie Bobby Brown's Must Haves: From an $18 Body Mist to a Bedazzled Water Bottle

Last but certainly not least, it's no surprise that when it comes to travel, Brown reaches for a favorite from her own brand: the Love Core Hair & Body Mist ($18). "I travel so much, and I always like to smell nice and fresh after long flights or drives," she says. "Love Core is such a yummy, juicy scent that I love!"

This lightweight mist can be used on both your hair and body, making it a super versatile pick for freshening up on the go. It's perfect on its own or layered with other fragrances for a more customized scent. And it's not just for you — you can mist it on your clothes, bedding, or even your travel pillow to keep everything smelling sweet and cozy. Just steer clear of your face, and you're good to go.
