You can have narrow underbust and no waist, like a rectangular form, it does not necessarilly mean that if you have narrow waist your underbust ist also small and vice versa. There are different body types (apple, pear,rectangular,hourglass).Even If get 24" waist I still have a big rib cage, I am not that far from 24" and actually that would not make much of a difference, I don't even try to get narrower waist since it already looks really tiny, it would not be a problem to go an inch down on waist, but your bones remain the way they are. I don't want to post my pictures, but I am very skinny and 36" bust (would also be just an inch more) would not be busty on me even though my hips are exactly 36" and with 25"waist it is really not that far from the "ideal" 24". And yes, I think the shoulders change the way your breast appear more than waist. But for example a friend of mine is really small, has narrow shoulders, her breasts are full,well developed and round, but her underbust is simply too small and all in all her breasts do not appear big, you do need a bit of the width on your chest.
