Moneyman in more elaborate clothes (9)
I believe the answer is:
financier
'moneyman' is the definition.
(synonyms)
'in more elaborate clothes' is the wordplay.
'more elaborate' becomes 'fancier' ('fancy' can be similar in meaning to 'elaborate').
'clothes' indicates putting letters inside (inserted letters are clothed in others).
'in' inserted within 'fancier' is 'FINANCIER'.
(Other definitions for financier that I've seen before include "Person engaged in large money transactions" , "I can infer (anag)" , "Gnome" , "City man" , "Money transactor" .)
