Flaunting her fit figure in semi-sheer stockings while walking fans through her look, Millie stunned in fluffy over-ear headphones, channeling the "snow bunny" look mentioned in her video.

Scroll for the photos and video. The above look was shared on Millie's Instagram earlier this month as she went all "elf on a shelf" in a Santa-inspired outfit complete with matching boots and a hat.
Flaunting her toned legs while lounging around on the floor in one image, Millie highlighted her thighs and calves, modeling a boy shorts pair of white undies with a Y-Fronts finish. Wearing glossy, sheer stockings underneath while modeling her fuzzy lilac sweater, the Stranger Things star showed off a French manicure while sporting her hair down, adding large white headphones with a wintry, faux-fur finish.

Filming herself in selfie mode in one slide, Millie showed off her braless sweater, discussing it more as she said:
"I wanted to show you the comfiest sweater ever. This is our Snow Bunny Eyelash Sweater," adding that she "hates itchiness." Over on the Florence by Mills Fashion feed, a photo of Millie in the sweater came with a caption introducing the brand's "Snow Bunny era." Millie closed her gallery with another full-length view of her outfit as fans saw her in white stiletto heels. "Frosted & fluffy," the brunette wrote, throwing in tons of wintry emoji.

The above photo was shared on the Florence by Mills Instagram as Millie Bobby Brown posed on a super-soft, fuzzy white blanket while in the same cute outfit. "Is this collection live yet? Cuz I can't find it on the website," one keen fan replied.
Millie joins stars including moguls Kylie Jenner and Kim Kardashian, plus supermodel Emily Ratajkowski, in retailing clothing. "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," the actress told Elle last year.
