Left one's bed and dressed (3,2)
I believe the answer is:
got up
'dressed' is the definition.
(getting up is a kind of dressing)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for got up that I've seen before include "Arose" , "20 [ROSE]" , "Ascended" , "made to look good?" .)
