Top part of a dress (6)
I believe the answer is:
bodice
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">top part of a dress</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 bodice that I've seen before include "Top of a dress above the waist" , "Close-fitting top of a dress" , "Upper part of woman's dress" , "Top part of a dress" , "Sexually explicit historical novel" .)
