It's black tie, but it's in a council run sports centre. I expect I'll hate it, but I've agreed to go on the basis that I've never been to such an event and the man who's invited me is rather lovely. He knows someone who's fighting.
I have a beautiful long silk evening dress that I've worn for pretty much every back tie event for the last 20 years (not many tbh) but wonder if it will be too much for this event? I'm really not inclined to spend money on it though.
