There is something endlessly entertaining about the classic celebrity “What’s In My Bag?” segment. From crumpled movie stubs to limited-edition lip balms, it is the perfect chaotic window into their everyday fabulousness. These glimpses feel oddly personal, like discovering that even the most glam superstar carries a half-eaten granola bar or loose change. It is a fusion of glamor, randomness, and reality, often with a side of tissues and uncashed checks. And now, this spontaneous sparkle is landing squarely in New York City.

Millie Bobby Brown is channeling that same infectious energy, bringing star-studded surprise and playful authenticity to New Yorkers.

Millie Bobby Brown, armed with charm and a lavender-scented mission, took to New York City for Florence by Mills’ latest Instagram escapade. Her opening line, “What’s in my bag?”, proved more than playful banter, it unveiled her new Coastal Chic Hair and Body Mist, a tender blend of sea mist, golden amber, and creamy monoi oil, bottled like summer caught mid-breeze.

Starting off the interview in an art gallery in Soho, she probed scent choices with strangers, then wandered outward, gathering secrets, opinions, and hair advice. A woman preferred brunette, a view Millie Bobby Brown’s husband Jake Bongiovi echoed, prompting her mock pledge to commit. She ended with a grin and a “mist-ery” bag, daring viewers to guess its hidden wonder.

From scent debates to surprise gifts, the entire outing captured her flair for curiosity, connection, and all things related to a bag reveal.

Millie Bobby Brown has consistently approached product promotions with a unique mix of charm, fun, and playfulness. From sharing her favorite fragrances to showcasing the Coastal Chic Hair and Body Mist with vocals and vibes, Brown has made her promotional moments feel like an extension of her authentic self. While celebrities like her are often associated with iconic, polished campaigns, Brown has chosen to take a more personal and spontaneous route, turning product promotion into an exciting What’s In My Bag? moment.

This approach is not new for Brown. She first teased the fun format when promoting Florence by Mills' collaborations, such as the Florence x Delsey Paris collection. Whether it was sharing her personal essentials or providing a behind-the-scenes look at her daily life, Brown has made the What’s In My Bag? segment her own. It allows her to blend humor and authenticity, proving that promotions do not need to be stuffy or scripted; sometimes, a bit of lighthearted fun is the best way to connect with an audience.
