Isabel Marant Etoile ruffle detail chambray top

Chambray long sleeve top with ruffle detail and zip up front. There is a mark on the front that looks more like an anomaly in the fabric and not a stain but I did take a few close ups of it, and it does stand out a little, there is also some stitching missing in the front. no other flaws. Pit to pit- 16.5” Length- 22.5”
