Millie Bobby Brown Wears Princess Polly Dress at Miami Open

Millie Bobby Brown sat courtside on Thursday for the women’s semifinal at the Miami Open. The Florence by Mills founder watched Aryna Sabalenka defeat Jasmine Paolini during the final stages of the tournament, alongside her husband Jake Bongiovi and father-in-law Jon Bon Jovi.

Brown opted for a touch of springtime with her wardrobe. The actress and producer wore a sleeveless minidress with a red stripe motif. The shift dress featured a boatneck and slightly flared skirt.

At times, Brown added a white sweater overtop her shoulders, which perfectly complemented the white stripes juxtaposed with the red color motif of the dress. Brown accessorized her look with a pair of retro sunglasses in a berry red colorway. She also wore metallic hoop earrings.

Both Brown’s husband and her father-in-law opted for casual attire, wearing crewneck T-shirts in dark tones. While the “Livin’ on a Prayer” singer added a pink baseball cap to his look, Brown’s husband went with a pair of sporty shades to complete his casual ensemble.

Brown’s time at the Miami Open comes after the actress and UNICEF Goodwill ambassador wrapped her “Electric State” press tour, for which Brown wore several designer looks courtesy of stylist Ryan Young.

At a screening of the film in New York City on March 11, Brown opted for a design courtesy of Tamara Ralph’s fall 2024 couture collection. The strapless black dress featured a thigh-high slit with the base fabric featuring a classic silhouette. Sculptural floral elements were added to create definition for the piece.

Brown’s promotional tour for the Netflix film coincided with the launch of her brand Florence by Mills’ new sportswear collection. On the collection, the actress and entrepreneur shared, “I love athleisure and sportswear so I wanted to create a collection that was just that. Stylish pieces that, of course, you could wear to the gym but for those of us who never quite make it there, we still look fab.”
