How to make boobs look closer together for prom dress?

Try running some tape (duct cut in half lengthwise, or good masking) over your boobs and diagonally like a "V". You'll have to experiment with the angle. Not sure if you're planning for your man to see/fondle your boobs later (not really my business), but the tape may make them a little gummy. A quick scrubbing should fix them right up though! Good luck.

While you are sitting in class or at home watching tv, push them together either with your hands or with your arms. When you are sleeping maybe tape them together so that they are always close to each other. Eventually, your boobs will naturally be really close together. Kind of like how your hair starts to style itself after doing the same thing with it over and over again, or how if you make an ugly face towards someone you have to stop in order to make sure it does not stay ugly.
