when to get first ever bra?!

I was like you :) I saw all my other friends with their first bras and I really didn't know if I should get one too. Bit of advice? Don't go out and buy the most adult bra they do in the younger section. Stick to what is comfortable :) Ease yourself into puberty and then it won't seem as scary. If you try on the bra and decide you don't like it, don't buy it. Or just buy one or two and see how you go for a while. You might decide you're not ready. I wasn't. I waited a little longer and then started again with a training bra. Whatever you do though, make sure you do try it on. Perhaps you could get you mum or the fitting room assistant to help you make sure you have the right fitting. There's no need to get embarrassed :) Just do what feels right :D Good Luck!! :) x

Experience :)

Whenever you feel ready to start wearing a bra. I got my first one with my best friend in the summer holidays between Year 6 and Year 7, so I would've been 12 too. How do you know that you're a 30A? Have you been fitted, or do you think that from trying on bras? I would get fitted if I were you, I know it sounds scary, but its the best thing to do. They also do it through your top, there is no taking off tops involved.
Talk to your Mum about it, I'm sure she'll be glad to be a part of it xx

My bra experiences - I'm 13, almost 14 and have worn a bra for about a year and a half.

Whenever you're comfortable with wearing one. You can ask your mom for money and to bring you, or you can ask to go with some friends or something. It's usually better to go with your mom the first time because she'll know what to get. Since you're not too big yet, you don't need too many. Get a couple comfortable sports bras and a couple regular ones. I got my first one when I was pretty much the same as you, so around now is the time if you like.

If you feel like you need a bra get one, Only you can decide when you need one, Maybe start with something like a training bra or if your not ready for a bra wear crop tops maybe? Go and get one with your mum she has been through it or go with your friends! Hope this helped x

I was wearing a bra at your size, and I was younger than you at the time. Go to a normal shop with your Mam, there's no need for special fitting, and just go from there.
Hope this helped.

Been there, done that.

when they start to jiggle and hurt when you run.

you should start wearing one now
