Super Girl dog costume, excellent condition

Super cute, officially licensed super girl costume for a dog. This is a medium, but it's definitely for smaller dogs. The manufacturer's size chart is above, but I think this would be best for a dog on the lower to middle weight listed (11-15 pounds), because it does not have a velcro closure. My Italian greyhound wore this. It is still listed for sale on Amazon, so the reviews there may be helpful for sizing. This is in excellent condition, other than a manufacturing defect on the print of the small S on the round circle on the underside (pictured).
