<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fashionable clique</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 in-crowd that I've seen before include "Clique considered by others to be fashionable" , "Small group of popular people" , "Fashionable group" , "Fashionable coterie" , "Cool people" .)
