ahh yes. my friend from high school only wanted to be in the sorority that had the same colors as our high school because she already had lots of clothes in those colors. sure enough that's where she ended up, although i hope she had a few better reasons by that time.
as for pref dress, i wore an all black dress and felt like a dork since i matched all of the sisters. i sure wish GC (and the Internet in general!) had been there for me in 1990!
