Really struggling with this - almost as though it was not the usual setter! Some I think I have the answer but can't fully parse, e.g. 6d "Topless female only coarse to be of interest", where I had were ?N?R?S? - so it ought to be engross I suppose, which is "to be of interest". Topless female is the usual domestic fowl less "h", and "gross" is "coarse" at a pinch. Where does "only" fit in? Guess I'm reading it wrong!
