Breasts and Bras
A New Stage in Life
Some girls can't wait for them to come and look forward to their arrival, but other girls dread them. But most girls have mixed feelings and aren't quite sure why they have them and what to do about them. Boys don't have them, but they're likely to be curious about them.
What's the mystery subject? We're talking about breasts. If you're a girl, look down and there they are — or will be soon. They're only two mounds of flesh, but they get a lot of attention. As a girl matures and goes through puberty, breasts tell the world that this girl is leaving girlhood and entering a new stage in her life.
Because large breasts get attention (just look at magazines, TV, or movies), some girls may worry if their breasts are small. Girls with large breasts also may be unhappy because their shape attracts attention they don't want. The truth is that beauty doesn't come in only one bra size. There are all sorts of female shapes and sizes in the world, and all are beautiful.
But breasts do more than look nice. Girls have them so they can do an important job later in life. Someday, if the girl grows up to have a baby, her breasts can provide the milk the baby needs. Breast milk is the very best food for babies and mom is the source. And it doesn't matter if those breasts are small, medium, or large. All sizes can produce enough milk to feed a baby.
When Do Breasts Start Growing?
Most breasts can start growing as early as age 8 or as late as 13. Some girls' breasts grow slowly and others grow quickly. Some girls may feel like their breasts will never start growing. But girls start developing at different ages and different rates. One girl might have more developed breasts at 12, while her friend could be still flat as a board.
Breast development happens in stages. The first stage starts during the early part of puberty, when a girl's ovaries enlarge and estrogen, an important female hormone, begins to circulate in the body. Doctors often refer to the early stages of breast development as "breast budding." Get it? Budding — like a flower has buds.
A breast bud is like a small raised bump behind the nipple. After breast budding happens, the nipple and the circle of skin around the nipple (called the areola) get bigger and a little darker. Then the area around the nipple and areola starts to grow into a breast.
As breasts keep growing, they may be pointy for a while before becoming rounder and fuller. For some girls, one breast might be a little bigger than the other one. A girl's breasts may continue to grow during the teen years and even into her early twenties. Fully developed breasts come in all shapes and sizes.
Breast size gets a lot of attention and many girls may wonder how they can make their breasts grow faster or bigger. There isn't any magic cream or pill that can speed up the process or make a girl's breasts larger than they are. In fact, heredity and a girl's weight mostly determine breast size. So if a girl's mother has big breasts or small breasts, the girl can expect to have breasts of similar size. And a girl who has more body fat is more likely to have larger breasts.
Getting a Bra
Once a girl has breasts, a bra is a good idea, especially when the girl is exercising and playing sports. Bras can protect breast tissue and keep the breasts supported. Some girls may also like that bras smooth out their silhouettes and make them feel more comfortable. A bra can make a girl feel less exposed when she's wearing a light shirt, such as a T-shirt.
Some girls look forward to getting their first bras, but others dread it. Like anything new, wearing a bra can be tough to adjust to. They can be hard to fasten and adjust. When a bra is on, it can bag or gap, ride up, dig in, or pop open. The straps can slide off a girl's shoulders or dig into them. And a bra can peek out of a girl's clothing. Not only that, but a girl's brother might think it's just hysterical to pull it so it snaps against her back. (If you are a boy, do not do this!)
The ABCs of Bra Sizes
Wearing the right size bra can decrease the number of other problems a girl will have with her bra. For instance, a bra that's the right size won't pinch, gap, or slide around. So it makes sense to spend some time learning about bra sizes.
Bras come in many sizes, which are different combinations of the chest sizes and cup sizes — 32AA, for instance. It's important to get both the chest and cup sizes right to ensure a proper fit. Some bra makers now also offer cup options in half sizes to help girls get a better fit.
What Size Bra to Buy?
A girl might feel shy about her growing breasts and not want other people talking about them, looking at them, and measuring them. But it's wise for a girl to get measured so she knows her correct bra size.
The women who work in the bra departments of stores can help a girl with this measurement. A girl also can do it at home if she has her mom or a friend help her. Here's how to do it:
- Run a tape measure just under your breasts, all the way around your back and ribcage. The tape measure should rest flat on your skin and lie straight across your back — not so tight that it digs in, but not so loose that it sags down in the back.
- Make a note of your measurement and add 5 inches. That's your chest size.
- To measure cup size, take the tape measure around your body across the fullest part of your breasts.
- Write down this number and subtract your chest measurement from it. The difference between the numbers is a way of figuring out your cup size. If the difference between the two numbers is less than 1 inch, your cup size is AA. If it's 1 inch, your cup size is A; 2 inches, you're a B; 3 inches you're a C, and so on. For instance, if your cup measurement was 33 and your chest measurement was 32, that's a 1-inch difference. Your bra size is 32A.
- If your chest measurement comes out as an odd number (such as 31 inches or 33 inches), it's usually a good rule to round down to the next number. Most bras have a few sets of adjustable hooks and eyes, so you can adjust the tightness. It's a good idea to round down, rather than round up, since bras tend to stretch over time.
What Kind of Bra to Buy?
A first bra used to be called a "training bra" — it was for girls who didn't yet fit into the cups of standard-size bras, but needed basic support and comfort.
These days, many girls' first bra is a sports bra, a type of bra worn by active women of any age. Sports bras prevent breasts from jiggling around when a woman is playing sports or exercising. Because they're flatter in the cup area, sports bras also make good first bras for many girls. In fact, because of sports bras, and dresses and tops that have built-in bras, a girl might not need a training bra or a more traditional bra early on. Not all sports bras are alike, so a girl should try on a few to figure out which ones she prefers.
Besides sports bras, there are a lot of other types of bras. The most natural-looking bra is a soft-cup bra, which doesn't do much to change the shape of a girl's breasts. Soft-cup bras come in different fabrics and thicknesses and some may have an underwire. Underwire is a U-shaped wire inside the fabric that goes under the breasts to help support them. If a girl's breasts are C cup or larger, an underwire bra is a good choice.
Other bras may have more structured cups and some come with padding inside. Minimizer bras are also available for girls who want their breasts to appear smaller. These bras are usually made of thicker fabric with bigger backs and straps.
A Girl's Changing Shape
Breasts are just one sign that a girl is getting older and on her way to becoming a woman. If a girl has questions or concerns about breasts or bras, the good news is that there are plenty of women and older girls to ask.
And if a girl is worried about how slowly her breasts are growing, her doctor is also a good source of information. More often than not, a girl is developing normally and before she knows it, she'll be bra shopping too.
