How do I get bigger boobs without surgery?

Really the only way to get bigger boobs is to gain weight. But even then, you can't control where the fat will go—it might end up someplace other than your breasts. Unfortunately, there's not a lot else you can do as breast size is based primarily on genetics, and hormones and weight can also play a part. It's also possible that your breasts may still grow on their own through your 20s, though!

Unfortunately the size of your boobs is mostly determined by genetics. There's not much you can do to make them naturally a lot bigger on your own. You could try doing chest exercises to build muscle under your boobs that will make them appear bigger. This only sometimes works though. It depends on your body type. If you end up losing a bunch of weight from working out, your boobs might actually shrink.

I don't think you can make your boobs bigger by eating certain foods or vitamins. But you can make them look fuller by wearing push-up bras or adding padding to your bra! You can also look for clothing that accentuates your chest and gives the illusion that they are bigger than they actually are.
