I really liked these pajamas on my son. The material appears to be of good quality. My son will be 5 years old and wears an XS (4) but I ordered a size 6 knowing that this type of pajama is rather tight fitting. The pajamas fit him perfectly, a bit loose but it's what I wanted in case they shrink in the wash. The order even comes with a thank you note along with the seller's email in case you are not happy with your order which I think is a nice gesture. I will definitely order again. I posted some photos. I hope it helps
