Millie Bobby Brown Showcases Her Latest Intimates Collection
The actress, aged 21, highlighted her figure by modeling the latest underwear line for Florence by Mills Fashion. Posing confidently, she revealed a fresh color variation that is now available on the brand’s official website. The bold shoot left little to the imagination and set social media abuzz, with many fans commenting on her style and poise.
Sporting a Striking Blue Ensemble
Brown appeared in a soft blue two-piece set, consisting of a tank crafted from lightweight material, allowing the Enola Holmes actress to effortlessly display her sculpted midsection. The cropped tank’s delicate fabric made clear that she was not wearing additional layers underneath, exuding relaxed confidence. The lower part of her outfit included high-rise briefs that complemented the top, accentuating her frame and offering a modern, minimalist look.
With the waistband sitting just below her belly button, the ensemble highlighted the young designer’s focus on both comfort and style, demonstrating the versatility intended for Florence by Mills fans.

Inside the Stylish Photo Session
The images were taken in a luxurious bathroom setting, featuring sophisticated amenities such as a bathtub, television, and enclosed shower. Brown positioned herself beside the sink, one hand resting on the counter as she snapped her selfies. She wore her hair loose, stacked on shiny rings, and showcased a polished makeup look to enhance the campaign’s visual appeal.
Marking the occasion and emphasizing the underwear’s appeal, Brown pointed out that she was wearing a brand-new shade, including a link for her followers to purchase the featured design.
Expansion from Beauty to Fashion
2024 marks a pivotal year as Brown’s Florence by Mills project moves from cosmetics into the fashion sector. When speaking with ELLE about this shift, Brown shared her personal journey and what fueled her decision to enter the clothing industry.
“I never thought I’d explore much with florence, but the more I moved, I thought, ‘Oh my gosh, I can do anything I put my mind to,’”
—Millie Bobby Brown, Florence by Mills founder.
“Anything that feels authentic to me, I can create for people that are like me. Whatever I want or whatever crosses my mind during the day, I think maybe somebody else is thinking too, and if I can create that and be that outlet, that’s very rewarding.”
—Millie Bobby Brown, Florence by Mills founder.
Defining Her Personal Style Journey
Reflecting on her career, Brown explained that the rapid success of Stranger Things thrust her into the spotlight at just ten years old, bringing her to major events and ceremonies styled by prominent fashion brands. She faced uncertainty about her personal fashion identity, mentioning that outside formal occasions or work, she rarely dressed up by choice.
As she matured, the need for self-expression through style became clear. Unlike many of her peers, Brown discovered her own preferences over time and views fashion as constantly changing. She believes that clothing should be adaptable, allowing young people to try new looks and experiment with evolving tastes.
Brown’s goal with Florence by Mills is to offer accessible fashion resources for her generation. She hopes that when young women shop, they find a dedicated space—however modest—where they feel represented and can afford meaningful pieces that suit their personal journeys.
The Lasting Influence of Brown’s Fashion Direction
Millie Bobby Brown continues to inspire through her evolving roles as both an actress and entrepreneur. By introducing Florence by Mills underwear photos in such a public platform, she not only boosts her brand’s visibility but also shares her hopeful perspective about self-empowerment and authenticity in fashion. As her brand expands, many anticipate further innovations designed to resonate with a new generation seeking connection, creativity, and comfort in their everyday wardrobe choices.
