Adorable pair of somewhat vintage ( dated 2009-2012) One Piece Fleece Zip Up PJ's.  These are of the popular Angry Bird Series.   The size reads Small 3/5, for that reason I am assuming  that these are for a junior size young lady.  Item is excellent witih no teatrs, holes, stains or repairs.  Coming from a Pet and Smoke Free Home.    The measurements are as follow:

From Underarm Seam to Underarm Seam  18"
From Shoulder Seam to Ankle Elastic   57
