Los Angeles, California - Millie Bobby Brown has expanded her florence by mills empire with a brand-new fashion line!

After expanding into the world of coffee last year, the 19-year-old star is kicking 2024 with another major power move.

On Thursday, Millie unveiled florence by mills fashion, a colorful new clothing line featuring sweatshirts, sweatpants, and more.

"I've always believed that fashion is a powerful form of self-expression, and I'm so excited to share a piece of my heart with you all today," she said in the announcement video.

The Enola Holmes actor described the apparel line as "a blend of playful and versatile styles and, above all, confidence and revolution."

In the footage, models gave fans their first peek at the brand's pastel-colored loungewear.

Millie dished on what fans can expect from the line in an interview with ELLE, where she revealed that the inspiration came from her own love of comfortable yet stylish clothing.

"I wanted to create really stretchy, soft materials that girls felt comfortable with going to school, going to work, things like that," Millie said. "I want people to feel like they're wearing pajamas, but they're able to go outside."

The Nineteen Steps author added that she hopes the brand will feel timeless, opting to avoid fleeting trends and instead use the fashion to elevate one's personal style.

"Everyone has their individuality," she explained. "Everybody sees things in a different perspective, and I want people to be able to really form their own style, opinion, perspective with florence, whether that be with makeup and skin care or with our apparel or with our coffee."

The first collection is set to drop in February, and those looking to get their hands on a piece can join the waitlist now at florencebymillsfashion.com.
