[AlphaSigOU]

Only initiated members of Alpha Sigma Phi may wear or display items with the coat-of-arms, shield and stylized 'Phoenix Mark' with Greek letters. A pledge may wear clothing with the three Greek letters. As for our badge, the only non-member who can wear it is the wife or the fiancee of a member, though we encourage them to wear the Sister Pin.

Our chapter wasn't a big stickler on being protective over our letters, but at the time when I was an undergrad, we were pretty small. Most fraternities at the University of Oklahoma usually collect chapter-issued items when a pledge depledges or a member is suspended or expelled, usualy accompanied by a warning to not wear any clothing or display any items from the fraternity.
