Cut some out for dress (7)
I believe the answer is:
costume
'dress' is the definition.
(costuming is a kind of dressing)
'cut some out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'cut'+'some'='cutsome'
'cutsome' with letters rearranged gives 'COSTUME'.
'for' acts as a link.
(Other definitions for costume that I've seen before include "Clothes for a play or fancy dress ball" , "Clothing" , "Outfit" , "Actor's attire" , "Attire worn in a play or at a fancy dress ball" .)
