Make sure you wear good support, you won't have anything to worry about.
Or you could take the lazy road and get a boob job. 
"The doctors will try to tell you that the world will love you better,
If you let them cut your body, put them mounds inside your sweater.
But think of the investment and how long those things will last,
Because silicone is permanent, even after you have past.
So when the rest of you is fading in a box under some stones,
You'll still have the silicone balancewd on your bones.
She got a boob job, yeah
She put a pad of silicone up against her breast bone, treat it like a man made thing"
