All your friends wear bras and i dont im 12?

There are a few reasons why you might not be wearing a bra yet while your friends are. It could simply be that you haven't started developing breasts yet, or that you're not at the stage where you feel comfortable wearing one. There's also the possibility that your friends are wearing bras for different reasons, such as modesty or peer pressure.

In any case, there is nothing wrong with you, and you should not feel pressured to wear a bra if you're not comfortable doing so. When considering wearing a bra, there are a few factors to think about, including your physical comfort, your emotional well-being, and your personal preferences. It's important to remember that every person's body is unique and that there is no one-size-fits-all approach to puberty.

Here are some additional things to consider when deciding whether or not to wear a bra:

- Your physical comfort: If you find that your breasts are bouncing around or causing discomfort, a bra can provide support and help you feel more comfortable. On the other hand, if you don't feel any discomfort, there's no medical reason to wear a bra.

- Your emotional well-being: Some girls feel more confident and secure wearing a bra, while others feel restricted and uncomfortable. It's important to listen to your intuition and do what feels best for you. If you're feeling self-conscious about your breasts, talk to a trusted adult for support.

- Your personal preferences: Some girls simply don't like wearing bras, and there's nothing wrong with that. If you don't want to wear a bra, there's no need to force yourself to. You can always choose to wear a cami, tank top, or other type of clothing that provides coverage without the restriction of a bra.

The decision of when to start wearing a bra is a personal one, and there is no right or wrong answer. If you're not sure what to do, talk to your mom, a trusted adult, or your doctor for guidance.
