Stripped duke finished hiding uniform (7)
I believe the answer is:
denuded
'stripped' is the definition.
('denude' can be a synonym of 'strip')
'duke finished hiding uniform' is the wordplay.
'duke' becomes 'd' (abbreviation).
'finished' becomes 'ended' ('end' can be a synonym of 'finish').
'hiding' is an insertion indicator.
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'ended' going around 'u' is 'enuded'.
'd'+'enuded'='DENUDED'
(Other definitions for denuded that I've seen before include "Stripped" , "Laid bare" .)
