Money earned, from such in-stock garments? (5-4)
I believe the answer is:
ready-made
'stock garments?' is the definition.
'ready made' can be an answer for 'stock' (I've seen this before). I am not certain of the 'garments?' bit.
'money earned from such' is the wordplay.
I cannot really see how this works, but
'money' could be 'ready' (ready can informally mean cash) and 'ready' is found within the answer.
'earned' could be 'made' ('make' can be a synonym of 'earn') and 'made' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for ready-made that I've seen before include "Of standard shape or size" , "Prefabricated" , "Instantly available" , "Commercially produced, not bespoke" , "Of clothes, mass-produced in standard sizes" .)
