<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">woman's shirt</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 blouse that I've seen before include "Garment like a shirt" , "Woman's upper garment" , "Obelus (anag) - buttoned top" , "Female garment" , "Shirt-like garment for women" .)
