Wat can i eat or do to make my breast bigger? im 18 and my bra size is 36 a please help

Nothing, : Nothing, 36 is the size of your torso and the cup size is the letter. If you want more to be firmer and larger consider fat injections.

Breast augmentation: When girls go through their pubertal growth, their breast growth is linked to that. If your frame is 36 and your cup size is smaller than a b and your pediatrician or pcp feels that you have normal development otherwise then unfortunately nature hasn't given you adequate sized breasts and you will need the expertise of a plastic surgeon for breast augmentation.
