So I know attire goes on the bottom right of invite, but my conundrum is wording.
We're going for black tie, but don't want to require it. A lot of our friends have tuxes and ballgowns on hand. So this is a great excuse to wear them. Other friends would love the chance to use rent the runway. And I know some consider "black tie optional" more informal. Not what we're going for. We're going for black tie if you have it or want to, but don't feel bad showing up in a nice cocktail dress or suit if you can't swing it (or feel free to put the kids in something a less formal).
Something I saw recently was "Black Tie Encouraged". I think that more conveys what we're looking at, but I've never seen the wording on an actual invite so don't know if it's uncooth.
Thanks in advance for your help!
