Dressed up and ready to go? (2,4)
I believe the answer is:
in gear
I believe this clue is a double definition.
'dressed up' is the first definition.
(I've seen this before)
'ready to go?' is the second definition.
(I've seen this before)
'and' is the link.
(Other definitions for in gear that I've seen before include "Having shifted" , "Engaged" , "Performing effectively" , "Out of neutral?" , "like moving heaps?" .)
