Millie Bobby Brown steps out in sheer black lace and fur with husband Jake Bongiovi

Millie Bobby Brown is on a high-fashion hot streak.

The “Stranger Things” actress, who turned 21 last month, is blossoming into a fashion star, bringing her sartorial A-game to the global press tour for her forthcoming sci-fi adventure film, “The Electric State.”

Last night, Brown stepped out in New York City with husband Jake Bongiovi in tow, showing off her sultry side in a sheer underwear-revealing black lace gown, complete with a faux fur neckline and cuffs.

Bongiovi, meanwhile, covered up in a Louis Vuitton zip-up jacket and jeans.

This week, the British actress has been channeling the iconic Fran Fine — much like Sabrina Carpenter, who has worn items directly from the hit sitcom.

Appearing as a guest on “Today” on Tuesday morning, the actress wore a Versace dalmatian-print skirt suit.

Brown pushed the outfit a step further with the addition of a cropped fur jacket, beret and shiny platform Mary Janes.

Later, on her way to “The Drew Barrymore Show,” Brown hit the streets in another eye-catching skirt suit, this time a monochromatic cream look with a jacket boasting a feathered collar and cuffs.

She styled the two-piece look with white sheer tights and complementing pumps.

On the red carpet, however, the A-lister went with a more avant-garde getup for a screening of “The Electric State” in New York, opting for a couture black gown.

The Tamara Ralph dress featured stunning rhinestone-covered floral accents wrapped around the bodice and neck.

Another stop on the press tour circuit was a sit-down interview with Alex Cooper for her “Call Her Daddy” podcast, where the Florence by Mills founder revealed she was wearing a cropped T-shirt of her own design and blue bedazzled pants that once belonged to Pamela Anderson.

According to the actress, Anderson gave her the bottoms — and other clothing from the “Baywatch” star’s personal wardrobe — for the press tour after she reached out for permission.

“The whole film is based in the ’90s, so I want everything I really wear on this press tour to be ’90s archive,” Brown declared.

Indeed, the mogul has been wearing Anderson’s clothes as well as a sheer Giorgio Armani dress previously worn by Gwyneth Paltrow.

Elsewhere in the podcast, Brown discusses her blond hair, which she debuted on Instagram in early February.

Though she’s rocked the shade in the past, Brown says this time around her husband isn’t quite a fan.

“Jake’s like, ‘you look totally different to me.’” She continues, “I sat in the chair for 13 hours getting my hair done and walk into the room and my dad was like ‘oh.’”

Brown also reflects on shaving her head for “Stranger Things,” reaffirming that she can’t wait to do it again.

In fact, Brown is eager to do it again before she gives birth to her first child. “It was really liberating; would suggest it for anyone, any girl.”
