So, Karen -- Did you decide? What did you end up using?
Well, and IF you are still thinking about it, I wanted to throw the old standby "Cocktail Attire Preferred" into the ring, in case you want something still on the classier-side, but not "over the top" formal. That is what I am going to use for my AHR, which is a bit more casual since the hours are from 12:30 pm - 4:30 pm/during the day, but it's still taking place in a ballroom, so it needs to be a blend of formal and casual. I'm hoping most everyone has a pretty good understanding of "cocktail attire" means...
Anyway, just a thought! Good luck!
