Possessing hats from Washington? (6)
I believe the answer is:
owning
'possessing' is the definition.
('own' can be a synonym of 'possess')
'hats from washington?' is the wordplay.
I cannot really see how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is found within 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 owning that I've seen before include "Admitting" , "Possessing" , "Possesing" , "Being in possession or confessing" , "In legal possession of" .)
