Custom; garment (5)
I believe the answer is:
habit
I believe this is a double definition.
'custom' is the first definition.
(I know that habit is a type of custom)
'garment' is the second definition.
(I know that habit is a more specific form of the action garment)
(Other definitions for habit that I've seen before include "Custom or monk's robe" , "Dress - custom - practice" , "addictive practice" , "Settled tendency" , "can cause addiction" .)
