Ages 6-8 More Detail
A bra is a piece of clothing worn under shirts and tops that fits over the chest. It is designed to support and cover the breasts. When girls go through puberty, their breasts start to develop, and many girls begin wearing a bra for comfort and support.
There are many different types of bras. Training bras and bralettes are soft, stretchy, and do not have any padding — these are often the first kind a girl wears. Sports bras are designed to hold everything in place during running, jumping, and other active movements. As girls get older, there are even more styles to choose from.
People wear bras for a few different reasons. A bra can make someone feel more comfortable, especially during physical activity. It can also provide a layer of coverage under thinner shirts. Some people find that wearing a bra just feels better than not wearing one as their body develops.
There is no specific age when you have to start wearing a bra. Some girls start wearing one around age 8 or 9, and some do not start until they are 12 or older. It depends on when your body starts developing and when you feel ready. It is completely a personal choice.
If you think you might be ready for a bra, talking to a parent or guardian is a great first step. They can help you figure out what type would be most comfortable and take you shopping to find one that fits well. Getting your first bra is a normal milestone of growing up.
Ages 9-12 Full Explanation
A bra is an undergarment worn on the chest that provides support and coverage for the breasts. As breasts develop during puberty, many girls find that wearing a bra makes them feel more comfortable, especially during physical activity. Bras come in a wide range of styles and sizes to fit different body types and preferences.
Most girls start wearing a bra sometime between ages 8 and 14, depending on when breast development begins. There is no single right time to start — it depends on your body and what feels comfortable for you. Some girls want to wear a bra as soon as they notice changes, while others wait longer. Both approaches are completely fine.
When you first start out, a training bra or bralette is usually the most comfortable option. These are soft, flexible, and do not have underwires or heavy padding. Sports bras are another great option, especially if you are active in sports. As you grow, you may want to try different styles to figure out what works best for your body.
Getting the right fit matters a lot when it comes to bras. A bra that is too tight can be uncomfortable, while one that is too loose will not provide much support. Many stores have fitting guides or staff who can help you find your size. Your bra size will likely change as you continue growing, so it is a good idea to check the fit every few months.
Starting to wear a bra can bring up a lot of feelings. You might feel excited, embarrassed, proud, or a mix of all three. If some of your friends are wearing bras and you are not yet, or if you are the first one, it can feel awkward. Just remember that everyone's body develops at its own pace, and there is no rush.
If you think you are ready for a bra, or if you are not sure, talking to a parent, guardian, or older family member is a good place to start. They can help you figure out what you need and make the shopping experience comfortable. Wearing a bra is simply a practical part of growing up, and there is nothing to be embarrassed about.

Tips for Parents
A bra can be a challenging topic to discuss with your child. Here are some practical tips to help guide the conversation:
DO: Follow your child's lead. Let them ask questions at their own pace rather than overwhelming them with information they haven't asked for yet. If they seem satisfied with a simple answer, that's okay — they'll come back with more questions when they're ready.
DO: Use honest, age-appropriate language. You don't need to share every detail, but avoid making up stories or deflecting. Kids can sense when you're being evasive, and honesty builds trust.
DO: Validate their feelings. Whatever emotion your child has in response to learning about a bra, acknowledge it. Say things like 'It makes sense that you'd feel that way' or 'That's a really good question.'
DON'T: Don't dismiss their curiosity. Responses like 'You're too young for that' or 'Don't worry about it' can make children feel like their questions are wrong or shameful. If you're not ready to answer, say 'That's an important question. Let me think about the best way to explain it, and we'll talk about it tonight.'
DO: Create an ongoing dialogue. One conversation usually isn't enough. Let your child know that they can always come back to you with more questions about a bra. This makes them more likely to come to you rather than seeking potentially unreliable sources.
