Free People Bird print mini dress

NWT sz 4, but the sz tag fell off. Bird print mini dress with button back and open detail. Lined. Side zip. It is a hidden zipper, and is coming undone at the very bottom part of the team that covers the zipper ( pic 6). A very easy fix for somebody who has a needle and thread handy. I would fix it myself, but all of my sewing supplies have been packed up for the move at the end of the month. H2o67gg
