Take off costume (5)
I believe the answer is:
strip
This clue might be a double definition.
'take off' is the first definition.
(stripping is a kind of taking off)
'costume' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
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" .)
