Penguin costume

In good condition, penguin Halloween costume. It says it fits kids sized 7-10, but I'm a grown adult, 5'8" and a size 14, or adult large/extra large and it fits me great! I think if a kid wears it, it is meant to run big, as can be seen in the second to last picture. A few small staines on front white part of penguin, but barely noticeable! Penguin feet are velcro and go over shoes. The undersides are stained black from touching the grown, have been washed and are barely noticeable under shoe!
