Those who sketch pants (7)
I believe the answer is:
drawers
'pants' is the definition.
(synonyms)
'those who sketch' is the wordplay.
I cannot quite see how this works, but
'who' could be 'dr' (from TV series Doctor Who) and 'dr' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for drawers that I've seen before include "pants" , "designers" , "Undergarments" , "Underpants or sketchers" , "Could be a chest of them but they're worn lower down" .)
