Ah, lets go back to the 60-70's!
Much more formal as far as dress went on Campus!
Dress was semi formal for guys, coats and ties for meetings.
Meeting days were every Tuesday night and we wore appropriate attire on campus and meetings. Let the Campus know who we were!
Weekends, oh well, look out as that was fun time!

But, letters were worn on T-Shirts once again to let them know who were are/were!
Now!

They wear beer, or shoes, GAP, Old Navy shirts!
That really promotes GLOs!
