Brie Larson is feelin' groovy. She's singing her fave Billie Eilish songs on IG, keeping up with fans on her super popular YouTube channel, and (rumored to start) filming a 'Captain Marvel' sequel as early as next week.

Now with new hair this MCU she-ro looks like she belongs on the third episode of 'Wandavision.' The 1970s are getting a major wink from Brie's styling team, and people have a lot to say about it.

She Went Full Fawcett

Check out the actress sporting a feathered blowout almost identical to what Farrah Fawcett wore as one of 'Charlie's Angels' in the 1970s.

"Cosplaying as my 70s doppelgänger," she writes in the post's caption. Like wide-legged pants, chunky platforms and middle parts, fluffy feathered hair is a popular part of 2021's free-spirited fashion vibe. Vogue's current issue calls '70s Street Style' a trend to watch, and we're watching it look pretty great on Brie.

Famous Friends Love It

Some notable people are living for Brie's look. Artist Alia Penner and podcaster Krista Smith commented that it was pretty, and the post got love from Rachel Zegler who's about to play Maria in Steven Spielberg's new 'West Side Story.'

Predictably, fans are also smitten. Notable comments include ones that appreciated the vintage theme ("Three’s Company vibes and I dig it") and ones that showed serious Brie Larson devotion ("please cosplay as my wife"). Dream big, everybody!
