Alum...
1. At least once a week. Its really starting to get cold in Oregon now and I need my sweatshirts to keep me warm! More if I get some of those presents (jewelery) I have been asking for.
2. I wear a lot of blue anyway... but not specifically for phi sig reasons... although one of my sweatshirts is our colors.
3. Way to much!
I wear it for my position specific stuff on advisory board. But, since I wear pin attire four days a week at work, I wear it a little more often. Maybe once a week or so. On casual day, I usually wear my foundation pin from rosebud society.
