Many wouldn't know that these bras were originally developed to shield the breasts of sportspersons at the time of training. Now they are hugely in demand by girls who wish to increase their bust size and look fuller. You can choose the kind of padding in terms of thickness and where you want it positioned. An all-over padding design will augment the breast shape while padding at the base of the cup will form an attractive cleavage by pushing the breasts upwards. Additionally, they could be worn to eliminate nipple definition or nipple-show.
