Correct me if I'm wrong -- in the post-college world, I've always understood that NPHC sororities have a much more prominent role than NPC sororities have traditionally had. It seems that there is a TON of prestige (I'm not sure if that's the exact word I want, but I'm too lazy to pick up the thesaurus that is about five inches away) that comes from being a member of an NPHC organization, whether someone is in college or has graduated. As a result, I think adults have more incentive to, in one way or another, try to associate themselves with organizations of which they are not members. As far as I know, that sort of thing is VERY rare with NPC organizations, and I think it helps explain why we often have differing opinions on the issue of non-members wearing letters.
