Fine plant in a female organisation, perhaps (5)
I believe the answer is:
wispy
'fine' is the definition.
(I've seen this before)
'plant in a female organisation perhaps' is the wordplay.
I cannot quite understand how this works, but
'plant' could be 'spy' (a plant can be a person positioned to act as a spy) and 'spy' is located 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 wispy that I've seen before include "Straggly" , "Lacking in distinction" , "Light and fine in texture" , "Slender and delicate" , "Diaphanous" .)
