Body wrapper (4)
I believe the answer is:
skin
'body wrapper' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for skin that I've seen before include "Swindle" , "Outer covering" , "Outer layer of, eg, apple" , "Outer layer of a fruit or vegetable" , "Peel; drum head" .)
