Millie Bobby Brown is embracing her inner fashionista. Brown, 21, reflected on her favorite looks of 2025 via Instagram on Tuesday, December 30, sharing that one of her top contenders was a braless moment. "My 'no-bra needed' shirt," the Stranger Things star captioned the post, alongside a link to her Florence by Mills shop. In the photo, Brown sizzled in a plunging black top finished with long sleeves and an off-the-shoulder neckline that slipped down her arm. Brown teamed the crop top with matching mid-rise spandex shorts.
