My understanding of the dress code came about essentially through a process of trial and error. Shirts with lettering were forbidden. Tank tops were forbidden. Skirts that were deemed 'too short' (an infuriatingly vague classification) were forbidden. And then there was the real kicker: no denim. Jeans were a second skin for me up to this point and my entrance into this sea of khaki horrified and nauseated me to the core.
