That's not always the case. You can't find greek letters at my current school, nor could you buy them at my undergraduate institution.

Since I only became a Phi a few months ago I only have one Alpha Phi shirt, and I only wear it to the gym. It's getting pretty skanky though. :p But I also kind of feel like I'm getting a little old to wear any shirts with collegiate/greek logos on them - and that includes my beloved red hooded sweatshirt.

I promote my affiliation in different ways. I have an Alpha Phi magnet on my locker, I write with an Alpha Phi pen, I drink from an Alpha Phi tumbler when I'm in class, and my security badge for my building is attached to an A Phi lanyard. I'm hoping to buy some subtle A Phi jewelry some day, and I'm always trying to create an occasion where I can wear my badge.

That polo sounds really cute! I'd definitely like a polo with my letters on it, where'd you get yours?

I still wear all of my shirts from college, and my collection is still growing because the collegiate chapter that I help advise now also makes a point to get me shirts from their bid days, formals, etc. I'm proud to wear them and the girls love to see my "older" shirts that they've never seen before. To them, it's cool. :D
