Cut some out for stage wear (7)
I believe the answer is:
costume
'stage wear' is the definition.
'costume' can be an answer for 'wear' (costume is a kind of wear). I am not sure about the 'stage' bit.
'cut some out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'cut'+'some'='cutsome'
'cutsome' with letters rearranged gives 'COSTUME'.
'for' is the link.
Can you help me to learn more?
(Other definitions for costume that I've seen before include "Clothing" , "Duds" , "ensemble" , "Theatrical clothes" , "(Historic etc) dress" .)
