Review: This set was perfect for our son's costume this year. 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: Very good quality and will be great for when my son plays hockey
