Carson's outfit? (3)
I believe the answer is:
kit
This clue is a double definition.
'carson's' is the first definition.
(I've seen this in another clue)
'outfit?' is the second definition.
(kitting is a kind of outfiting)
(Other definitions for kit that I've seen before include "In strip" , "Football top, shorts, stockings and boots?" , "Young beaver" , "Set of articles or tools" , "Specialised clothing or set of parts for assembly" .)
