Inaccurately cut some clothes (7)
I believe the answer is:
costume
'clothes' is the definition.
(costume is a kind of clothes)
'inaccurately cut some' is the wordplay.
'inaccurately' indicates anagramming the letters.
'cut'+'some'='cutsome'
'cutsome' anagrammed gives 'COSTUME'.
(Other definitions for costume that I've seen before include "Clothes for a play or fancy dress ball" , "Attire worn in a play or at a fancy dress ball" , "Rig" , "ensemble" , "Actor's attire" .)
