Unfinished state leaving you red-faced (6)
I believe the answer is:
florid
'red-faced' is the definition.
(I've seen this in another clue)
'unfinished state' is the wordplay.
'unfinished' means to remove the last letter.
'state' becomes 'florida' (US state).
'florida' with its final letter removed is 'FLORID'.
'leaving you' is the link.
(Other definitions for florid that I've seen before include "Over-elaborate" , "Ruddy in appearance" , "Pink or ruddy in complexion" , "With flushed complexion" , "Excessively ornate" .)
