The answer is "yes", you can have bigger breasts if you really want to, but it depends. This questions is more likely being asked by women, and there is more likely to be asked by a girl whos' not in her 20's yet. The idea is that, for example, if you're 10, it's just normal to have a flat chest because you're body is not grown up yet, so don't worry about it. If you're 30's and you have a flat chest, then there may be a problem and you have to do something about it, really fast. The society may associate bigger boobs with beautyness but it's necesary to do this for you in order to feel ok. Let's talk a little about different methods of getting bigger breasts, natural or even surgical:

• I've seen that most girls (in their 17-18) tend to use a lot of herbal remedies in order to get bigger boobs, but this may not work pretty well. I don't say that they won't work for you, but in the cases I know, it does not really work.
• breast augmentation
• saline implants - it can cost up to $5000 but it depends on your region or where you're making it, and different other options, it's just a hint
• silicone implants - I guess that this is the most known idea of making bigger breasts but it could cost up to $5000-$7000 so it's not cheap at all. Breast augmentation is a surgical way to get bigger boobs and it may not be cheap for a regular teenage girl.
• implants - this are not so natural, we've been talking about salline and silicone implants, but the idea is that most of the women make this kind of deal in order to look more confident and to feel better about them, it's your choice.

   Another way to answer your question about how to get bigger boobs will be to get to know and understand the society. Most of the girls would feel not so confident and embarassed about themselves because of having small breasts, but the idea is not about them, it's about the society beauty model and the idea of having "normal" breasts would make them look beautiful and stuff. It's like being skinny or overweight, it's normal to get and try to fix it, if you can, even you if can't you're going to try to fix it, but until you really fix it try not to fall in depression or other complexes because you're not going to help yourself. Help yourself by trusting yourself and not the society you're living in, try to know what to answer if a boy is laughing about your boobs and take care of yourself. Do not try to satisfy the others, try to satisfy yourself because the life is big and you do not have the time to satisfy the others.

   I want bigger breasts: yes, you could. But, if you're to young, having a flat chest, you should not, you may have to wait. It's normal for some people to have small breasts and for other people to have bigger breasts, but with today technology you could cheat and have bigger breasts to. Take care of yourself and be sure you take the good decison!
