A1: There is no direct conversion, but a 65G is roughly equivalent to a US 30G or a UK 30G . A 65 band is a US/UK 30 band (65 cm ≈ 25.6 inches). The cup sizes are similar, though the letter progression is different because Western sizes use DD and DDD, while Korean sizes do not.

Korean and Japanese bra manufacturers often design cups with a shallower projection to cater to the average local anatomy. For a woman with a full, projected G-cup, shallow cups cause a "compressed" look or push breast tissue out toward the armpits, even if the label claims to be the correct size. 2. Excessive Padding Trends

In the standard metric sizing system used in South Korea, Japan, and continental Europe, a G cup represents an overbust-to-underbust difference of approximately 24 to 26 centimeters .

To decode a 65G cup under the Korean Standard KS K 0050 , the size must be broken down into its two core structural metrics: the band and the cup.

In popular media, a "G cup" is often associated with a heavily amplified, plus-size frame. However, on a 65 band, a G cup looks remarkably proportional and distinct. Because the frame is so petite, the breast tissue is projected forward rather than spread across a wider chest wall. This mismatch between societal perception and structural reality often leaves women feeling confused about their true size, leading them to wear compression sports bras or ill-fitting cups that flatten their natural shape. 3.
