Revealed, suitable set of clothes (6)
I believe the answer is:
outfit
'set of clothes' is the definition.
(I've seen this before)
'revealed suitable' is the wordplay.
'revealed' becomes 'out' (I've seen this in other clues).
'suitable' becomes 'fit' ('fit' can be similar in meaning to 'suitable').
'out'+'fit'='OUTFIT'
(Other definitions for outfit that I've seen before include "Organisation or set of clothing" , "Full set of clothing" , "Cohesive unit, eg a military company" , "Garb - equipment" , "suit" .)
