Wilderness Technology boys goose down jacket size 7

This is a great coat that is warm but not too heavy. It is in good used condition. There is a stain in the front and a discoloration on the left arm. There are no holes or any other defect that I am aware of other than the stain and discoloration. Please see the photos. This coat has a tag that says size 7 although the measurements are 14.5 inches from pit to pit, and 17 inches from shoulder to waist line. Please check the measurements against a similar item that you know will fit your kiddo, as kids sizes vary widely.
