Garments easily disturbed (6)
I believe the answer is:
livery
'garments' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for livery that I've seen before include "colours" , "The care of horses for pay" , "Uniform worn by menservants, chauffeurs, etc, often part of a retinue" , "Feeding and stabling of horses for money" , "Fancy dress for footmen" .)
