I bought these pajamas for my 11 year old who is between 12 and 16 depending on the brand and it's his dream. He loves how soft they are, fit well, not too big and not too small. Order the size your son is wearing and it should fit perfectly. I ordered size 14/16. I have a feeling it will last until his next growth spurt. For the price you pay more for the brand but the quality is worth it. This is good quality fabric. The shirt is made of elastic material and the pants have an elastic waistband, also elastic. I definitely recommend it.
