In the gents outfitters, chaps say naughty things (8)
I believe the answer is:
'naughty things' is the definition.
The definition suggests a singular noun which matches the answer.
'in the gents outfitters chaps' is the wordplay.
I cannot really see how this works, but
'gents' could be 'men' (gent can mean a man) and 'men' is located in the answer.
The remaining letters 'swear' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'say' is the link.
Can you help me to learn more?
(Other definitions for menswear that I've seen before include "Gents' clothing" , "clobber" , "it covers their bodies" , "Male clothing" , "Y-fronts, among other things" .)
