Review on NACOCO Cute Dance Lion Dragon Pet Costume: Red Yellow Sequins New Year Cat Dog Clothes Hoodies Coat - Perfect for Small, Medium, Large Dogs by Jennifer Alvarez

Fits very well. I was guided by the chest circumference and the body length. The neck size listed was much larger than my pup's neck circumference, but I went ahead and took the risk. I'm so glad it really fits that well. My only complaint is that the dragon's head tends to tilt to one side. I think instead of 1 clamp it would be better if there were 2 or even 3 of these to hold the dragon head in place. I would probably sew it up myself so the dragon head doesn't tilt too much. So that's 1 star. Here are my pup's measurements and he fits a size 20 nicely. Chest Diameter 24" (61cm) Neck Diameter 13" (33cm) Neck Base to Tail 19" (48cm)
