Millie Bobby Brown In Tight Underwear An '11' With Her 'Thigh Gap'

Millie Bobby Brown proved a hit in her unbuttoned shirt and tight underpants as she went all "Couch Date" on Instagram back in February. Earlier this year, the Florence by Mills Fashion founder promoted her 2024-launched brand in selfie mode, flaunting her4 fit figure in a leggy look while rocking florals. Showcasing her enviable physique in a boy-short pair of undies, Millie coordinated her red underwear to pops of red on her floral-print shirt, one she wore unbuttoned for a racy finish. When fans on Instagram reposted the snap, one user couldn't help but comment on the British star's "thigh gap window." Another, meanwhile, ranked her an "11!"

Scroll for the photo. Modeling a white, button-down blouse covered in romantic rose prints, Millie sent out Valentine's Day energy in her long-sleeved look, ditching her pants as she flaunted her legs in super-tight briefs.

The Stranger Things star, who is also the founder of her best-selling Florence by Mills cosmetics brand, posed from an indoor space and backed by a rail of more of her brand's clothes, gazing into her phone while wearing her brunette hair down.

Adding sexy red kitten heels with an open toe, Millie clutched a pair of shades, wearing a ring, and a lightweight layer of makeup. Millie had debuted her Couch Date collection in striped PJs as she lounged around with takeout pizza, telling her Instagram followers:

"It's true, I'd rather stay in. Couch Date Collection is HERE and it's my love letter to all the homebodies at heart." This time, the actress featured on a fan feed, where comments poured in fast. "Look at Millie," one user said. "Look at that thigh gap window…," another wrote, with a third dubbing the mom of one an "11."

Millie Bobby Brown's fashion brand is all about comfort, cute pastels, and Gen-Z energy. In this promo shot, the actress admired her reflection in front of a mirror, modeling a knit-effect pink crop top and matching, rollover pants with a leggings feel.

"For me, fashion has always been ever-evolving. It's fluid, and I wanted to create something so that girls going through that similar experience have a resource to be able to try innovative new outfits and styles and phases. I wanted to be able to create something that was accessible to my generation," she told Elle. Millie joins fellow celebrities, including Kylie Jenner, Kim Kardashian, and Emily Ratajkowski, in retailing apparel.

In this selfie, Millie Bobby Brown showed the results of her gym sessions, showcasing her impressive abs in dark gray undies with a braless crop top. The actress has spent recent weeks promoting her brand's Softie Seamless collection.
