Chafing

Jessica
Any recommendations to help with chafing? I'm going to Vegas for a bachelorette party and the bride wants us wearing dresses every night 👎🏽. 
I already know my thighs are going to be sweaty and rubbing together. I don't want to wear Spanx because they'll be a pain to pull up and down while I'm drunk and having to pee every few minutes. When I wear underwear that are like shorts they roll up. 
Sorry I'm being complicated. LolÂ
