Until I joined this site I never knew that the formality of an event was set by the invitation. Every invitation I've ever gotten I have just marked the date on my calendar and sent in my rsvp without a thought to the style of the invite. I'm not sure what subtleties I'm supposed to be looking for. Now having said that, I've always managed to dress myself appropriately to any occassion I've attend. I default evening coctail dress unless told otherwise. But as I'm shopping around for invites it has me wondering what message mine will send.
I would like my event to be semiformal. (read as men in slacks and blazers, women in coctail dresses or pant suits). My event is evening but I don't want guests to feel like they need to rent a tux or buy a full length gown. I really don't know what cues people pick up on in invites that would make them dress one way or another. what should I avoid so guests don't get the wrong idea.
I really don't care how guests dress. I just want people to have a good time and not feel over or underdressed when they get here.
