Kitty with sweatshirt pulled up (3)
I believe the answer is:
pot
'kitty' is the definition.
(both can mean a shared fund)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pot that I've seen before include "Container for 23" , "Receptacle" , "Kitty; marijuana" , "Plant holder" , "It may call the kettle black" .)
