My D's school has Winter Recruitment but they were given the dress requirements at the end of the Spring semester as the recruitment outfits for the actives are approved (or not) before T'day break.
Winter is a bit different than summer as the weather is colder and the girls are a bit more "covered." No manis/pedis are built into the dues (my D wishes!
) but the actives are required to wear closed-toe pumps and of course stockings throughout rush.
I agree about the strapless awkwardness. We were at a college function last night and way too many young women were yanking at their dresses....
