Yes it will, especially playing sport, bouncing up and down, running etc as you will stretch the muscle bonds that hold the breast muscle and fat to your chest wall, as well as stretching the skin. You could wear a padded bra if you want them to look bigger. Always get a bra fitting.
I know it can be embarrassing, but it can make a huge difference to be wearing the right size bra.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
