Take off costume (5)
I believe the answer is:
strip
This clue might be a double definition.
'take off' is the first definition.
(I know that strip is a kind of take off)
'costume' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
Can you help me to learn more?
(Other definitions for strip that I've seen before include "Band; unclothe" , "Take off clothing" , "Ribbon" , "Undress completely" , "Series of cartoons" .)
