Thought this was a perfect Everyman in terms of difficulty and clever, satisfying clueing. Really enjoyable.
My only difficulty was with everyone's COD - 8a, as, although I'm a Londoner, I had no idea where the Royal Courts of Justice are, so that part of the clue was baffling to me! I needed my OH's help with that one.
Only one, minor, quibble - the DD in 15a - although it was easily gettable, strictly speaking it is not a gown, but something worn over a gown.
