I ordered a 6 because I assumed it would be a normal youth size 6 which would have given him room to grow in. It says 6 years on the tag and it is extremely small. A little sad because he was so excited and it is way too small. :( Great quality! I would just suggest going up a size or 2.
I purchased both the t-shirt and guitar for my grandson's Christmas present. I am very impressed by your service. Orders were fulfilled quickly and the delivery timeline was well communicated.
