Oh, I cannot stress this enough, please don't wear perfume!!!! When I went through rush, we were advised against it, but several girls wore it anyway. It was almost unbearable. Lots of the houses had scented candles lit and potpourri around their house and it was overwhelming. Combine this with several different perfume fragrances, and it's almost nauseating. NO PERFUME! If you must, wear a lightly scented lotion. And I had problems with sweaty hands. I know it sounds gross, but I wasn't the only one.
Fall Rush months in the South are guaranteed to be hot and humid, plus I had the jitters. I doused kleenex with baby powder and kept them in my pockets or purse so all I had to do was clench it for a few moments and I seemed calm as a cucumber. After I was initiated, I still used my kleenex trick b/c the rushees had the same sticky hands problem.
I know this isn't the most glamorous thread
but you just don't know how much more confident you will feel about shaking hands with hundreds of girls, if you have dry palms.
