Why are fans calling Brie Larson’s chest 'glass-cutting' in a resurfaced clip?

Fans have revisited a 2021 clip of Brie Larson wearing a tight, braless striped tank top, with social media users commenting that her chest could "cut glass." The footage, originally shared on Reddit five years ago, highlights the MCU actress's muscular figure and superhero physique.

Resurfaced Reddit Thread Details

The video shows Larson carrying a blue jacket with wet hair and a fresh-faced appearance. She wears a white tank top featuring lightweight blue stripes, showcasing her cleavage without a bra. This visual display has added to a collection of photos and videos emphasizing her physical condition.

One admirer reacted to the post by exclaiming, “Geez, those are some glass cutters, mama mia!” The original poster referred to her chest as “pokies.” Larson maintains a significant following on Instagram, where she is tracked by over 6 million users.

Muscle Gain for Captain Marvel

Larson is recognized for her defined biceps and triceps, paired with a layered haircut above the shoulders and minimal makeup. Her physique reflects the 15 pounds of muscle she added for her role in the 2019 film Captain Marvel.

This is not an isolated instance of Larson displaying her figure. Previous celebrations include paddleboarding in a bikini for her birthday and posing in swimwear to highlight her ripped muscles.

Public Reaction to Appearance

In another Instagram repost, Larson wore a low-rise bikini bottom and an open-chested tank top, displaying hip and thigh definition alongside printed swimwear. She also appeared in a lilac shirt, smiling while teasing her chest.

Reddit discussions from 2025 varied in their assessment of her look. One user described her as “a handsome woman,” noting she is attractive but “not super soft.” Another claimed she was “20 pounds underweight,” while a third stated she looks “adorable and still like a normal human.”

Hollywood Curve Comparisons

Larson’s online attention mirrors that of other Hollywood stars. Dakota Johnson’s removal of a bikini top in France was called “very very nice” by observers. Megan Fox faced questions about when “they got that big” in a string bikini, while Jessica Alba displayed her “milkers” in beachwear. Ariel Winter drew notice for “huge hooters” in braless street photos.

At a Miu Miu event, Larson wore a stylish playsuit that highlighted her gym-honed legs and arms. Although she is not signed to the designer fronted by Sydney Sweeney, she holds an ongoing endorsement deal with the brand.
