Cook's garb
I believe the answer is:
apron
'cook's garb' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for apron that I've seen before include "Protective wear - type of stage" , "Pinafore" , "Type of stage; pinny" , "Domestic protection" , "Kitchen garment or airfield surface." .)
