Breasts & Butt

This isn't meant to sound stupid but how do I make my boobs bigger? Are there certain vitamins or pills you recommend? Certain foods? My boobs are different sizes and my biggest insecurity, I've started going to the gym to work on my butt, I'm working 5 days a week to try and get an hour glass figure. Any food or tips or advice on how to get a larger butt and breasts?
