What can I do about my boobs?

Im so insecure about my boobs. First off they’re always popping out and you can see them so clearly from my shirts.

Second there’s stretch marks, and for some reason I’m fine with them on my thighs but I’m so much more insecure about my boob stretch marks. Maybe because it’s more noticeable or maybe it’s because I see them more often. Either way, I don’t like it. There’s also these red dots that stay there.. what is that about? They’re not pimples, they’re just flat red dots that never go anywhere. I have a few more on the rest of my body but it’s usually only one in an area and it’s barely noticeable. My boobs are just so pale, and for some reason there are more dots on my boobs and they’re in the same spot, so it’s extra noticeable.

I don’t know if this is just me, if I’m the only one that sees this, but it bothers me.

Does anyone recommend affordable minimizer bras? And is there a way to make my stretch marks less noticeable? Maybe tanning? And what are these red dots?
