Break the clue up a wee bit...
42 - refers to 42 Across
p - is p+
dress - another word/noun for this.
I got no help whatsoever from the title heading, Parky!
That gives 2 words for 31D.
Also have (I think) reasonable answers for 24D - 2 words, 4D - 3 words.
If 10D is a synonym for "pants" I'm still at sea. :-(
