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

Like many of us, Brown keeps an emotional support water bottle nearby — but not just any bottle. Hers is the Grenada Rhinestone-Encrusted Insulated Tumbler ($34), a 40-ounce, sparkle-covered statement piece. "Why not add some sparkle to your everyday?!" she says lightheartedly. The tumbler comes in a variety of bedazzled color options, making hydration feel a little more fun.
