push up bra=push in bra?

push up 係向上推,令到個胸唔受地心吸力影響搞到墬;
push in係將個胸向內推,矯番正八字波,同埋收番好腋下d肉去番個胸度;
兩者都係令個胸個shape靚d!

push up bra, to push your breast up and make a better shape and looks bigger.

push in bra, to push your breast inward, so the gap between the breast looks smaller.

Actually, push up bra also has the effect of a push in bra....
