How Are Other Girls Doing?

As mentioned, certain factors will determine the average size of 12year old breasts, so the bra size may change a bit as well. Here is what other young girls have to say about their growth pattern.

"While I was in my JUNIOR year, I wore an A size bra. I was 15 at that time. It all changed over the summer and I had to wear a 34B. I was in a 34C by the end of my senior year. If you are 12 and still have small breasts, do not worry."

"I have just turned 12 and I am already 5-ft tall. I am a size 32C now, even though my friends only wear a size30A or B. I believe the size of your breasts usually depends on how chubby you are.  If your mother started to grow breasts at very early age, the chances are you will experience the same."

"I really think it depends on weight, genetics, and even sports you do. I am only 12 and a half now and wear 36D. I had my first period in third grade, while most of my friends did not have one until in seventh grade. I do not think there is anything great about having big breasts because I cannot wear certain types of clothes and I have to hear rude names given by boys. Girls who do not have large breasts at 12 should not worry because they will eventually see an increase in their size. Just learn to love your body."

"I don't think there's an average size of 12 year old breasts. I am 12 now and wear 10E bra cup size. It was not easy dealing with this growth because all the girls in my school think I look at least 4 years older than my age. I feel quite embarrassed while taking swimming lessons at school. I can only play sports wearing a sport bra and another bra over it. I was 10C when I was 10 and have been wearing bra since then."

"I am 12 now with a 30A bra. While I definitely wish to be a big bigger than this, I believe the real thing is to love the way you are. I am not concerned about average size of 12year old breasts because I know that bra size does not matter a lot when you talk about real important things."

"I was a 32A when I turned 12 in January 2010. I am now 34B but usually wear strapless bra of 32B in size for a tighter feel. I believe the average breast size for a 12-year-old is between 32A and 36B."

Buying a Preteen Bra

Once you have some information about the average size of 12 year old breasts, you would want to know how to buy a preteen bra. This does not have to be very difficult though because you can find it at any department store. You can go to a store and ask a special saleswoman called a bra "fitter" to help you select a right bra for your child.

Girls can also go and buy a bra for themselves. If you are going to buy a bra for the first time, you should keep a few important things in mind. For instance, you will have to choose from a variety of bras.

  • Training Bras: These are designed specifically for girls who have very small breasts. They may have no cups at all or flat cups in some cases.
  • Sports Bra: It is quite like a training bra because it comes without cups, but it is usually a good choice when you want to keep your large breasts in place while playing sports.
  • Padded Bra: It comes with extra padding to help make your breasts look larger than they really are. They also add shape and cup size. Some of these bras are called "water bra" because they contain a gel like substance to provide your breasts with a more realistic look.
  • Push-Up Bra: It helps make your breasts look fuller and larger, but it does not offer good support.

Along with keeping these bra types in mind, you need to understand that you do not always need to go for the cutest bra, especially if it is not most comfortable one. Always go for a comfortable one to avoid adjusting your bra all the time. Also, bear in mind that bras come with different types of straps. Some of these straps are thick while others are extremely thin. Some may even have wire that goes under the breasts to provide additional support. Try them to see what feels most comfortable.
