How to convince my mum to let me wear a moulded cup bra?

Today we were just about to go to the mall and I was wearing this really loose top, and you could see my boobs through it 😕 my mum noticed and told me to put on my bra, it's one of those thin material ones. It doesn't cover anything and it's pretty much useless.

Do you think I need a moulded cup bra? It's a bra with a nice shape to it and gives extra support.

My boobs go up and down when I walk, my nipples haven't really came out yet but they are starting to, my boobs are really pointy and I'm a 34a.

How do I convince my mum to get me a moulded cup bra? Last time I asked which was about 5 months ago she said I was too young for one, but now she's always complaining about my boobs and she says I can't wear tank tops out. Do you think she wants me to start wearing a moulded cup bra? Please help 😕

Ask your mom to help you find an age-appropriate bra that no one can see through, and also keeps you from bouncing.

Well tell her that if you wear molded cup bras that there better for breasts than the other ones the other ones you just put on and it does no good and your breasts stil flop down tell her that the molded cup bras will A.give you support
B.it won't show your breasts
C.the other bras are practically a short shirt
