I believe the answer is:
man about town
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fashionable fellow</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for man about town that I've seen before include "City gent" , "Fashionable and sociable chap" , "Fashionable male socialite" , "Sophisticated socialite" , "Fashionable fellow" .)
