Koolaburra by Ugg 2-piece Lounge, Pajama Set V-Neck Pullover Top Jogger Hem Ankle Pants Blue and Coral Tropical Print 95% Rayon, 2% Spandex (very stretchy) Armpit to armpit = about 24 inches Pants Inseam = about 29 inches Waist = about 15.5 inches (please see the last picture - there is an oval shaped opening in the fabric at the back of the waist. I have no idea what it was for but it looks like it came that way. I cannot be sure because it's possible someone made the incision for some unknown reason. You can see the elastic through this opening. Overall this set is in very good to excellent condition.
