Caught boy getting dressed (4)
I believe the answer is:
clad
'dressed' is the definition.
(to be clad in something is to be dressed in it)
'caught boy getting' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'boy' becomes 'lad' (informal term for boy).
'getting' is a charade indicator (letters next to each other).
'c'+'lad'='CLAD'
(Other definitions for clad that I've seen before include "Cover with insulation" , "Wearing" , "Dressed" , "Attired" , "in dress perhaps" .)
