What is a Push-Up Bra?  

A bra with additional padding in the bottoms of it cups to lift the breasts for the iillusion of greater volume. Some have both bottom and side padding to both push up and in thus creating the look of even more cleavage. Putting on a push-up bra can be a little tricky.  You need to be sure to reach in and lift up your breast tissue so that it rests on top of the cup padding.
