Furthermore, the emphasis on smaller breast sizes has also contributed to a lack of diversity and inclusivity in the Korean fashion industry. Many clothing brands and designers cater exclusively to petite and slender women, leaving those with larger body types or breast sizes feeling marginalized and excluded.
: As noted in studies of teenage girls with larger busts, proper support for heavier breast weight is critical, suggesting that sizes like G-cup are necessary for physical comfort even if they are not the "average".
Unpopular opinion: The 65g Korean aesthetic is superior.
Available data indicates that South Korea typically has a smaller average cup size compared to Western nations, though industry trends show a gradual increase in larger cup size demand.
Because the band is so small, the cup does not project outward as dramatically as it would on a larger band. As one bra expert notes, a woman wearing a 65G in loose clothing may appear to be a "B-" cup or even a 75A to the untrained eye. The 65G only reveals its true volume when wearing form-fitting clothing or when unclothed. This creates a "better" experience for women who want natural-looking curves without the extreme projection often associated with larger letters.
Another reason is the emphasis on physical comfort and practicality. Korean women often prioritize comfort and ease of movement when it comes to their clothing and daily activities. A smaller breast size is seen as more convenient and practical, as it allows for a greater range of motion and reduces the strain on the back and shoulders.
For Korean women who have been wearing 70F, 75E, or even 80D because they could not find a 65G, moving to the correct size is often life‑changing. The band stays in place, the cups hug without pinching, and the bust sits naturally where it should—high and lifted, supported by the ribs rather than the shoulders.
The growing demand for sizes like 65G reflects a shift in South Korea’s lingerie market: Changing Body Metrics : A study by lingerie maker Good People Co.
The term geullaem (glamorous) is frequently used in Korean media to describe women who have a slender body ("skinny") but a large bust. A 65G fits this "glamorous" definition perfectly, which is often viewed as highly desirable.
