Baby Gap Cotton Overalls 12- 18 months

Gap Navy Blue Cotton Overalls with thin, striped lining. 12-18 months. Excellent used condition- worn once only. 100% cotton exclusive of decoration. 2 button adjustable shoulder straps and snaps in leg. Note: extra stitching near left shoulder strap button (see photo). It was there when purchased (bought new from BabyGap), not sure purpose but recall it was found on all the overalls? Wanted to give full disclosure as I originally thought it was a defect.
