How can I dress to look y even though I have small and a childlike body?

Try appeciate the fact you have a slender, childlike body as you can work more fashions than girls with real curves and bigger busts! Your body can probably get away with most styles of clothes and can be just as y (if not more so) than curvier or bigger girls. (: If however you want to give the impression of having more curves, wear bell shaped/full skirts or a waist-high pencil skirt with a wide waist-clinching belt. Halter neck tops (and bikini's) will create an illusion of a bigger bust (if that is what you want). Also, tops that have strings to tie around your waist and tops that clinch in will make you seem curvier (: Finally, though, iness is being individual, confident and loving yourself.
