Idle, wanting a chemise? (9)
I believe the answer is:
shiftless
'idle' is the definition.
(similar in meaning)
'wanting a chemise?' is the wordplay.
I cannot really understand how this works, but
'wanting' could be 'less' (I've seen this before) and 'less' is found in the answer.
'chemise?' could be 'shift' ('shift' can be a synonym of 'chemise') and 'shift' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for shiftless that I've seen before include "lacking in initiative" , "Like an automatic American car" , "Idle" , "Lazy - indolent" .)
