Cooks' garments (6)
I believe the answer is:
aprons
'cooks' garments' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aprons that I've seen before include "Protective garments for aircraft" , "Kithchen garments or airfield areas" , "Garments worn in kitchens" , "Areas for parked aircraft" , "Protective garment" .)
