Artist’s pants (7)
I believe the answer is:
drawers
'pants' is the definition.
(synonyms)
'artist's' is the wordplay.
I cannot really see how this works, but
'artist' could be 'ra' (Royal Academician, member of Royal Academy of Arts) and 'ra' is found in the answer.
This explanation may well be incorrect...
(Other definitions for drawers that I've seen before include "Knickers" , "pants" , "Old-fashioned clothes" , "Could be a chest of them but they're worn lower down" , "undergarment" .)
