Please describe the most effective way to naturally enlarge my breasts?

None: I would learn to love your breasts as they are. The alternative is breast augmentation surgery.

Bra/baby/inserts/wt: While bra insert sets are the best way to non-surgically enhance the breast, the only other natural way is to gain weight, get pregnant or lactate via natural methods. Hormonal manipulation may do this but is generally not recommended. On occasion, some women experience larger breasts with oral contraception. The brava or noogleberry external vacuum devices may also provide some enlargement.
