I believe the answer is:
maxi
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">long skirt</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for maxi that I've seen before include "what garment is not revealing?" , "Long skirt of coat" , "full length garment" , "Long dress" , "Ankle-length skirt" .)
