Really enjoyed a party, looking flushed (6)
I believe the answer is:
adored
'really enjoyed' is the definition.
'a party looking flushed' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'looking flushed' becomes 'red' (being red in the face).
'a'+'do'+'red'='ADORED'
(Other definitions for adored that I've seen before include "Idolised" , "Much loved" , "Worshipped and venerated" , "Worshipped, loved" , "Loved intensely" .)
