One more saying that is definitely hazing! Hell, I'd rather get swatted silly than go out of the house without makeup!!
If you all want to do it together, and have a lock-in where you all sit around in your jammies, that is fun, but to tell the truth, this pledges going without makeup thing was in a book I read about a high school sorority. You are not in high school anymore.
Not only that, if you are trying to appeal to the campus at large, it might uncover some scary things that people don't need to know. I love my sisters dearly, but God bless cosmetics is all I can say!
I'm including myself in that, too!
