Cook's wear (5)
I believe the answer is:
apron
'cook's wear' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for apron that I've seen before include "Pinny -part of the fairway leading onto the green" , "Area around aircraft hangar" , "Paved surface where aircraft stand when not in use" , "Protective garment - part of stage" , "Protective garment worn at front" .)
