Sweating + braidsmaid dress = help!

My armpits sweat really bad especially when I’m nervous. I tried on my bridesmaid dress for an altering and I sweated so bad so quickly you could see the wet marks on my dress under my arms. And I know I’m going to be nervous during the actual wedding. 😫

I’m currently using a men’s Degree deodorant that I thought was doing the trick. It has been over 8 hours since I applied the deodorant in the morning so maybe I just need to reapply a lot before the wedding?

Or is there a better deodorant out there or any ideas to help?
