What can a 17 year old do to lift up breast WITHOUT surgery?

One option to consider BluePeaches is Liposuction Breast Reduction. There are many benefits to Liposuction Breast Reduction compared to open surgical breast reduction. I does not leave scars on the front of the breast. Often no scars are visible at all. It does not interfere the possibility to breast feed. There is no risk to the nipple or blood supply.

If your breasts are very droopy then surgery is the only thing you can do to make your breasts perkier. You can try strengthening your chest muscles, which may make your breasts protrude more, however it won't be that effective. Your only option is a bra if you don't want surgery.

As my colleagues have told you, there is no breast lift without surgery. There is no exercise, cream, potion, or lotion that can tighten your breast skin, and that also includes hormones, lasers, RF devices, and other "miracle cures."I know you said you are feeling insecure about your breasts, but breasts come in all different sizes and shapes--part of what makes them so wonderful to partners of all different kinds. Trust me, there are plenty of breasts that look different from what you may consider to be "centerfold perfection," and they can be quite beautiful and desirable all on their own. But without photos or personal examination it is impossible to tell you that surgery might not be in your best interests, because at some point in your future, expert plastic surgery could indeed be an excellent option to improve symmetry, size, or perkiness of your breasts, if that is your desire. This would be considered elective and something you would ask for, so you would need to understand that surgery may add scars, cost money, and require the acceptance of (minimal, but potential) risks in order to improve the size, shape, or appearance of your breasts. That would NOT be "messing up" your body, and good plastic surgery can definitely boost self-esteem and confidence. But only if that is your choice and you willingly accept the "cons" in order to achieve the "pros." The only "natural" way (non-surgical) to lift sagging breasts is with a pretty bra. So until you are ready for surgery, don't worry about your breasts, and don't waste time or money searching for anything else. Honest!

To my knowledge there is no way keep the breasts in a lifted position when one is not wearing a bra without surgery

First, if you want a lift then you would need your parents' permission to see a plastic surgeon.  But there is no such thing as a non-surgical lift.

Good habits (especially for young breasts) include regular moisturizing and keeping your pectoralis muscles well toned.  Although these are good habits, they are not likely to significantly lift a breast.  Best of luck to you.

I agree you are a bit young to be undergoing a significant cosmetic surgery procedure, but there is no lift without surgery. However without an exam it would not be possible to give you specific options.
