In a recent interview, Sydney Sweeney opened up about her struggles with body confidence during her childhood, particularly due to her curves. She mentioned how growing up, she wore a size 32DD bra in sixth grade but felt self-conscious about her body and often wanted to hide. This lack of confidence impacted her self-esteem and body image significantly, making her feel that she could never find clothing that fit comfortably and made her feel good about herself.

Sweeney credits her role as Cassie in HBO's hit series 'Euphoria' for helping her transform her outlook on her body. Working on the show, she discovered the power of confidence and acceptance, which inspired her to embrace her physical appearance. She reflected on how the character helped her realize that bodies are worthy of appreciation and can be celebrated, leading her to a pivotal moment of self-acceptance and empowerment.

This newfound confidence motivated Sweeney to create her lingerie brand, Syrn, launched in early 2026. She identified a gap in the lingerie market for supportive and flattering designs that cater to different body types. Her personal experiences with insecurity serve as the driving force behind the brand, aiming to provide women with the confidence she once lacked and to promote the message that all bodies deserve to be celebrated and cherished.
