All's I can say is that this did not hold me up very much!  maybe a half an inch.  And that's not saying much because I am a B cup.  I bought this to go under my clothing I didn't want to wear a bra with (tube top) and bathing suit.  I've had a breast lift/reduction, so that's not the issue, it was just so it didn't look as though I didn't have a bra on.  Basically it just helped them not sway!  The adhesive wasn't bad though and didn't hurt to take off.
