Favoured worker collecting garment for resident (10)
I believe the answer is:
inhabitant
'resident' is the definition.
(I've seen this before)
'favoured worker collecting garment' is the wordplay.
'favoured' becomes 'in' (I've seen this in other clues).
'worker' becomes 'ant' (worker is a type of ant).
'collecting' means one lot of letters goes inside another.
'garment' becomes 'habit' (habiting is a kind of garmenting).
'in'+'ant'='inant'
'inant' placed around 'habit' is 'INHABITANT'.
'for' is the link.
(Other definitions for inhabitant that I've seen before include "One who stays in" , "One living in a place" , "One occupying a place" , "Resident" .)
