- The package has been slow to arrive: ordered the 10/12, I received it in extremis 24/12 - I ordered a size 5/7 years but the disguise is much too large. My son will carry the front 2 or 3 years. I informed the seller of this and he very kindly and quickly offered to return it for exchange. Unfortunately I threw the package. But if it can help someone order the right size ... The product itself is ok for the price.
