Help with outfit

Hey, just found this group and hoping you can help!

Im going to a party in a few days and the dress code is black tie. I’ve got HH bad on my palms and armpits, my dress is quite clingy so I won’t be able to dry my hands on it like I normally do with a t shirt for example. Does anyone have tips??

I don’t have time to get any medications/deodorants now sadly
