What would be recommended to tone or make my breasts smaller naturally?

You can't: There is no such thing as 'toning' your breasts. They are composed of glands and fat, not muscle. The only way to make your breasts smaller is through a breast reduction.

Weight loss: Makes them smaller no non surgical methods for toning sorry.

None.: There is no way to “tone” breasts up. Breast lifting refers to operations that will raise the breasts on the chest wall. Trade-off with breasts lifts are scars.

Weight loss: In some cases weight loss may help to reduce the size of the breast. This would be relevant to a person who is considered to be overweight. However if you are at your ideal weight, dieting and exercise may not significantly affect your breast size.
