On my campus, no one in any group wears block letters except for some of the professional orgs.
I've seen members of BGLO's and MCGLO's in crossing jackets every once in a while, but that's about it.
Guys in IFC frats never wear letters.
The NPC sororities wear party shirts and that's about it. And some groups wear party shirts far more often than others. Although I heard that this year it was mostly due to the fact that 2 sororities had t shirt chairs who got shirts in colors a lot of people really didn't like.
Window stickers on cars are HUGE down here however. Huge as in popularity, not in size
