<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">business attire</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for suit that I've seen before include "Eg, hearts or clubs" , "Hearts, maybe" , "Case < for outfit" , "Petition" , "diamonds, perhaps" .)
