I sweat far too much, no matter what temperature, no deodorants seem to work and it gets in the way of everything. In 4 weeks time I'm going to a school prom and my dress is just below my armpit, I know it's going to be hot, and i don't want my day to be ruined. Is there any way I can stop the sweating without getting surgery, or anything clear I can put underneath my armpit? Thanks.
