These type of clothes tend to flatten your chest (I guess the teachers want the guys to do schoolwork rather than look at girls). You could try tucking your shirt into your skirt, to make it tight against your chest, or if that doesn't work I think you need some chicken fillets (cup enhancers) or a push up bra or both.

Put socks inside your bra on the outer and under your breasts to push them together and up.
