On her website, Charms says that her bust size is 153XXX, and that her breasts each weigh 26 pounds (11.8 kg).
Charms has had breast augmentation surgery three times. The first augmentation enlarged her to an E cup, the second to an HH. Both were saline bags. The third surgery implanted the polypropylene string. In some cases of breast augmentation via the polypropylene method, the breasts may grow at different paces or at a dangerously accelerated rate. In her case, they have grown in unison, but their growth rate has steadily slowed over the years. The initial string content was equivalent to 2500cc. Her doctor estimates the growth has increased the size of each breast to over 7000cc.
When asked if her bust size causes her back pain, she replied that it does not if she keeps up with exercise. Her favorite authors are Ha Jin, Anne Rice and Charles Dickens.
