When will my breasts, hips and backside grow because they are to small?

You should love your body as it is. Wearing padded bras that are extreme like the bombshell bra are kinda unnecessary in my opinion as I have a friend who's in 8th grade and wears one all the time, it looks unnatural and imagine the embarrassment when you take your bra off and someone sees how you are truly. All in all, don't cheat yourself and act like yourself around guys and they'll probably take you, someone more natural and modest, over a young haughty looking girl who seems slutty and likes to flaunt what she has.
