Geez-- do I remember how to post a non-confrontational reply
Here in my part of the South, greek affiliation actually is a space provided on the form for wedding announcements. Unfortunately, they still put "...where she was a member of Alpha Chi Omega Fraternity for Women" -- even though I put in huge black lettering "I AM a member of AXO..." and highlighted it.
Our wedding announcements are still free though.
Oh, and they don't do the gown thing here -- they used to like when my parents got married years ago, but not now. Now its:
Mr. and Mrs. announce their daughter to...son of....the bride graduated....and was....the groom....bridesmaids were...groomsmen were...reception given at....rehearsal dinner given at....after a trip to....the couple will live in....
And that's that.
