They come with strings attached (6)
I believe the answer is:
aprons
'they come with strings attached' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aprons that I've seen before include "Garments worn in kitchens" , "Kitchen garments for cooks" , "Protective garment" , "Areas for parked aircraft" , "Protective garments for aircraft" .)
