Brown, put back in act, stripped (7)
I believe the answer is:
denuded
'stripped' is the definition.
('denude' can be a synonym of 'strip')
'brown put back in act' is the wordplay.
'brown' becomes 'dun' (dun is a kind of brown).
'put back' says the letters should be written in reverse.
'in' indicates putting letters inside.
'act' becomes 'deed' (deed is a kind of act).
'dun' reversed gives 'nud'.
'nud' going inside 'deed' is 'DENUDED'.
(Other definitions for denuded that I've seen before include "Stripped" , "Laid bare" .)
