Capitalist wearing garment with gold (8)
I believe the answer is:
investor
'capitalist' is the definition.
(investor is a kind of capitalist)
'wearing garment with gold' is the wordplay.
'wearing' becomes 'in' (wear in (and 'in' is fashionable)).
'garment' becomes 'vest' (vest is a kind of garment**).
'with' says to put letters next to each other.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'in'+'vest'+'or'='INVESTOR'
(Other definitions for investor that I've seen before include "Shareholder" , "angel" , "One putting money into shares, etc" , "One with stocks/shares" , "Isn't over for the one putting money into" .)
