All my party people

I am 18 years old and have stage 3 HS but I am NOT gonna let that stop me from enjoying my senior prom!

I want to dance the night away and be in a beautiful dress just like everyone else but ofc with this condition we have to modify that. I have flares on my armpits, under breast, and groan. Although I am not self conscious about my underarms, I do want to keep them hidden because I know I'll be sweating and draining. I was also thinking a very flowy dress instead of those tight ones everyone else wears.

My question is, for those who love to party despite having this condition, what are some tips you could give me to party with HS? What can I do to prepare prior to prom and what should I avoid the day of prom? And what do you take if you do take anything when you do party?
