Cut-off trousers (6)
I believe the answer is:
shorts
'cut-off trousers' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for shorts that I've seen before include "Summer trousers" , "Garment" , "Trousers that end at or above the knee" , "bottom gear" , "Item of clothing; drinks of spirit" .)
