Boob help 😭😭😭

I wear a 34D and have no idea how to keep them in place with a strapless dress. I have never found a strapless bra that doesn’t slide down my body as the night goes on, and I don’t want to keep pulling it up throughout the night for NYE.

I also have no clue how to use body tape to hold my boobs in place either.

I want them to look as perky as the can in my strapless dress; I hate when they look saggy. I just have no one in my life that knows how to do this stuff for a bigger chest so I really need help.
