How to tape my breast?

I got invited to a graduation party and the dress I have for it is strapless. I don’t have the budjet or the time to order a strapless bra that would be the correct size so I decided to try to tape my breasts but that doesn’t seem to work.

I am on the larget size, E-cups on the European scale and I need help or should I just go to the party braless but with nipple pasties?
