I've got an industry dinner to go to this weekend. I've never been before and as I'm going as a guest of my solicitors, I don't feel I can call up and ask "what are you wearing?" 
As far as I'm aware, it's pre-dinner drinks, dinner with entertainment from a band and then speeches before a singalong (It's a strange industry!) so no dancing, etc if that makes any difference, it's much more formal.
The industry is heavily dominated by males and there aren't many photos available from previous events so I can't even see what the standard is.
I have a long black dress with a split or a knee length black dress with a small sequinned panel on one side. Shoes I'm unsure of at the moment. Is it still the case that bare legs should not be on show? In which case this limits the shoe option somewhat!
I still haven't lost the baby weight so I'm a size bigger than normal which means these are my only two options as nothing else fits and I'm reluctant to buy something new.
So...what would you wear? Long or cocktail? I bloody hate Black Tie as a dress code!
