At my school, the biggest intramural sport is Football, and most sororites would wear something along the lines of their Bid Day shirts, so that everyone was matching. It was very common for fraternity boys to be the coaches for the teams. About 2 years ago, our chapter got really lucky, since our coach convinced a local restaurant to "sponser" us, and had actual jerseys made...they were a really nice black mesh/jersey material, with Chi Omega spelled out in red letters on the front outlined in yellow, and different numbers on the back, also red outlined in yellow. If you could find someone to pay for that for you, I definitely recommend it - I think we played so well because we knew we looked so good
and they were such a great quality that we'll be able to pass them down in the chapter for awhile...definitely an edge over the cotton t-shirts with slogans.
