"I bought this costume for my short (38 inches tall) 4 year old. Based on the size chart, I bought the 3T-4T size. I ended up exchanging it for a size 4-6 which fit perfectly. Other than the sizing I absolutely love this costume. It is adorable and pretty unique (in the sea of super heros and ninjas out there). The robe is great and he wore it (with the hood on) all day."
"This costume was perfect for my son. I bought the small size and it was his exact size (he is 38 inches tall, and weighs about 36 pounds). The quality of the costume was top rate, and he was comfortable every time he wore it."
