Jang Yoon-ju Openly Reveals Breast Size and No-Bra Preference

Model and actress Jang Yoon-ju has addressed long-standing rumors regarding her physique and personal choices in fashion, sharing details about her breast size and her preference for going braless.

According to a report from Star News published on May 2, 2026, Jang spoke openly about her body, stating that her breast size ranges from D to G cup.

The revelation comes as part of a broader conversation regarding the model’s approach to clothing and her decision to go braless, a choice she has described with a cool attitude toward public perception.

Addressing Plastic Surgery Rumors

Jang’s comments follow a history of public speculation regarding whether she has undergone breast augmentation surgery. In previous responses to such rumors, including content shared on her YouTube channel YOONJOUR, she has consistently denied these claims.

She has attributed her physique to genetics, noting that breast size runs in her family. In past statements, she mentioned that among three sisters, she is actually the smallest in the family.

This openness about her body is consistent with her previous appearances in media, such as the SBS Special titled Jang Yoon-ju’s Breast Story, where she shared medical details about her breast density to dispel surgical myths.

Perspective on Fashion and Comfort

Beyond the specifics of her measurements, Jang has discussed the evolution of her relationship with undergarments. She has previously mentioned that her choices varied by age, noting that in her 20s, she often preferred wearing items without cups.

By speaking candidly about the reality of her body and her choice to forgo bras, Jang continues to challenge conventional beauty standards and expectations placed on high-profile models in the Korean entertainment industry.
