Reveal more attractive clothes come from here (9)
I believe the answer is:
outfitter
'clothes come from here' is the definition.
(an outfitter sells clothing)
'reveal more attractive' is the wordplay.
'reveal' becomes 'out' (outing is a kind of revealing).
'more attractive' becomes 'fitter' (fit can mean attractive).
'out'+'fitter'='OUTFITTER'
(Other definitions for outfitter that I've seen before include "Men's clothes shop" , "Men's clothing shop" , "Supplier" , "One dealing in clothing" , "who could help in gear selection?" .)
