Wishing to go back to bed at first, got up (7)
I believe the answer is:
attired
'got up' is the definition.
('attire' can be a synonym of 'get up')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for attired that I've seen before include "surrounded by duds" , "Turned out" , "got up" , "Dressed or clothed" , "Wearing clothes" .)
