I wish more alumnae of NPC organizations would wear their letters. One thing I've always admired about BGLOs is the commitment after graduating from college. There are too many men and women who join sororities and fraternities, love them during college, and forget them afterward.
I usually wear a piece of silver jewelry to work with my letters on it. It's somewhat discrete, but if you're having a conversation with me, you can plainly read it. I like wearing it because sometimes it strikes up a conversation with another Greek, or, even more excitingly, another Gamma Phi.
I did recently wear my lettered sweatshirt to the store to grab popcorn with my boyfriend, and felt a little funny about it. If more of us did it, it'd be easier for all of us.
Though there is something to be said for upgrading to a classy alumna wardrobe

I'm less excited by t-shirts now than by classy sweaters, jewelry, or professional items (like portfolios, business card cases, etc.)
