Luxurious work uniform provided (7)
I believe the answer is:
opulent
'luxurious' is the definition.
(I know that luxurious can be written as opulent)
'work uniform provided' is the wordplay.
'work' becomes 'op' (abbreviation for opus).
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'provided' becomes 'lent' (I've seen this in other clues).
'op'+'u'+'lent'='OPULENT'
(Other definitions for opulent that I've seen before include "'Rich, luxurious (7)'" , "Let up on, being wealthy" , "'Deluxe, luxurious (7)'" , "magnificent" , "Well-to-do, rich" .)
