Right, I said "almost" any font. The problem with fonts like Lucida Handwriting is that so many people use them improperly that they are virtually tacky in my opinion. Same with stuff like Comic Sans. In most cases, I think they just look more tacky than elegant.
Edwardian is nice. Depends on how formal of a dinner it is. For most things, I prefer a minimalist invite with a serif (non cursive) font.
For graduation, religious ceremony and rites of passage type things I guess I could see Edwardian.
