Is there anything that i can do to get larger breasts without surgery?

Not really: Breast size depends partly on hereditary factors, female hormones, and amount of body fat. Hereditary factors cannot be changed. If a woman found an herb or supplement with hormonal effects of breast growth, there would likely be frightening effects on other parts of her body. If a woman got too thin, her breasts would get smaller due to loss of fat. Vacuum devices are sold, but are not natural.
