adhesive bras...I need your advice

Rachel
Alright ladies. In my friend's wedding in July in the south (aka, heat humidity and sweat) and the dresses are beautiful but pretty much backless (enough to not be able to wear a normal bra). All of my lucky friends who have smaller boobs love and use adhesive bras, but I'm a 34D-DD (depending on the brand) and I just don't know if they will work on me.
Thoughts on best brands that 1) will stay on through heat and sweat and 2) hold things together up there for people that have larger boobs?
Thanks ladies!! 💋
