Custom made clothing (5)
I believe the answer is:
habit
I believe this clue is a double definition.
'custom' is the first definition.
(habit is a kind of custom)
'clothing' is the second definition.
(habit is a kind of clothing)
'made' acts as a link.
(Other definitions for habit that I've seen before include "nun gets into" , "What might one have a regular tendency to" , "Custom; clothing" , "Settled practice" , "It's worn in order" .)
