Part of a dress (6)
I believe the answer is:
bodice
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">part of a dress</span>' is the definition.<br/ ><span class="explanation-format__explanation">('bodice' is part of 'dress')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for bodice that I've seen before include "Basque" , "Upper part of woman's dress" , "Close-fitting top of a dress" , "Corset" , "tight-fitting costume?" .)
