After reading some reviews, I ordered a size up (Medium) for our boy who normally wears a Small 5/6T. I wanted it a little lose not snug fit. It fits nicely in the waist and length on our tall ,lean boy. The material is good quality, color was bright and item just as described. Our son said is soft and comfy. Material is even softer after washing. Would definitely recommend for warm under clothing wear or pajamas! Review: Good buy - I bought for pyjamas. I have a very slender 11-y/o grandson. Bottoms are a little loose, but are fine for sleeping. My 9-y/o grandson is more average in weight. Fits good. They both are a little tall. I ordered large for both. Very soft and warm. Well made.
