Mostly it shoves everything upwards and adds a bit of padding. You can see the victoria secrets' models. They do not have even C cups boobs but they look to have. Go to victoria!.
It uses gel padding to make you wonder why you spent so much on a hot sweaty bra. Same way as any other bra works. It just looks better..
I don't think guys are supposed to know the answer to this question, it's there to make us 'wonder'.. and boy do we wonder. you put it on and it does wonders by making your tiny **** look big
