I agree that
www.universitygraphix.com is a good site to go to.
www.getsomegreek.com is a good one as well. Both sites off shirt designs that quite a bit more up to date on fashion trends as compared to the typical greek t-shirt printing websites.
Maybe it's just me, but I was still in school I thought the house with the obscene shirts were rather trashy. I never saw anything like that out of the stronger 150+ person houses on campus. I'm glad my TKE chapter was never interested in anything like that or I probably would have rushed somewhere else. Feel free to gang up on me all you want, but I think that shirts with obscenities or references to sex, drugs, alcohol, etc. don't attract the demographic that we need to be recruiting into our chapters. Make a first impression of being classy high-achieving gentlemen who strive for excellence in every way of life and then that's the type of man who we'll be recruiting.
