DH and I are going to a Change of Command ceremony for our good friend in a couple weeks. It also happens to fall on my birthday, so I wanted to dress up a little. But I noticed on the invitation, in one corner, it reads:

Uniform of the day
Civilian Informal

I can't suss out if this means the military people wear the "uniform of the day" and civilians dress "informal" or if "civilian informal" is a code that means the military people don't have to wear their uniforms that day. I looked up the term, and civilian informal seems to mean a business suit... however, nothing I read said anything about who the dress code applies to.

Any insight? I'd prefer to not wear a suit on my birthday, but I also will not purposefully break the rules for this event.
