My son is 11 and tall and thin so I ordered a size 12. When it arrived the tag said "12/8-10T". It was definitely more like 8-10. But worst of all were the proportions β very wide and very short. I don't know that a person has more width than length, especially at this age! The fabric seemed decent - regular cotton, but it wasn't particularly soft, which my son always likes. Very basic, not particularly "cozy".
