Do you want a fuller bust or a more noticeable cleavage?   Many of us instead of trying to locate a good style in a bra, choose to go for a bra size smaller to push the bust up,    There is not need to squeeze :)  simply look for plunge bras or push up bras, many come with light padding to help with your lift .   Push/plunge bras are made to push up and pull together, and many are very very comfortable to wear.
