This girl in my class is shorter than me, never wears bras, and she wears tight clothes.

Okay, so like, everyone's body is different and grows at its own speed. You might see girls in your class who look a little different or seem to be at different stages of growing up, and that's totally normal.

Some people start developing earlier, some later, and it doesn't always have to do with how tall you are. So like, some girls might already be wearing bras because their breasts have started to grow, and others might not need one yet, or they might just prefer not to wear one, even if they have some breast development. What people wear, like tight clothes or no bra, is usually just about what they feel comfortable in.

It's easy to compare yourself to other people, but your body has its own timeline for puberty and all the changes that come with it. The most important thing is how you feel in your own skin and to wear what makes you comfortable. And if you have questions about your own body and what changes to expect, you can always ask a trusted grown-up or check out the Soso app to learn more.
