Upper part of a dress (6)
I believe the answer is:
bodice
'upper part of a dress' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bodice that I've seen before include "Stays" , "Close-fitting top of a dress" , "Tight clothing" , "Upper part of woman's dress" , "Top of a dress above the waist" .)
