Millie Bobby Brown introduces a citrine colourway at Florence by Mills with a tenniscore-inspired look blending micro skirt, bralette and controversial heels.
With winter on the verge of surrender, Millie Bobby Brown is already stepping into spring, setting what may become 2026’s first major trend through her brand, Florence by Mills. On 12 February, the actress revealed on Instagram her latest chromatic statement: citrine. A vibrant yellow-green shade that not only nods to the aesthetic of Challengers, but is positioning itself as a strong contender for colour of the year.
The photoshoot, staged on a tennis court evoking country club glamour, reads as a manifesto of elevated athleisure. At its centre, a summer-ready pairing: the Softie Cotton Triangle Bralette and the Cozy Crush Mini Skirt. Rendered in citrine, the duo radiates energy and youthful confidence. Brown completed the look with a matching hood left open to reveal the bralette, and rectangular white sunglasses that injected a sharp, modern edge. As she declared herself: “Now serving my newest shade… citrine.”
Yet the real catalyst for debate — the detail that truly reframes the outfit — lies at her feet. In a move that challenges thematic logic, Brown swapped tennis trainers for pointed white heels. The boldness does not end there: layered over the heels, she wore slouchy wool leg warmers, a pairing reminiscent of a controversial 1980s styling trope that has resurged this season.
The choice feels intentional. Within the athleisure landscape, where comfort reigns supreme, introducing a heel becomes an act of subversion. It is the juxtaposition of sport and formality, casual and polished. The leg warmers add texture, warmth and a retro undertone that taps into 90s and early-2000s nostalgia. The result is a look that feels simultaneously cohesive and disruptive.
With this move, Millie Bobby Brown is doing more than unveiling a new drop — she is issuing a forecast. Citrine is poised to define the shift towards warmer months, and fashion is leaning freer, more experimental. The micro mini returns as a power piece, and athleisure steps into evening territory. The message is clear: there is no need to wait for the weather to change to dress the way you want. In citrine and leg warmers over heels, Brown is already living the summer we are all anticipating. Game, set, match.
