Today I received my pajama set. I have a more muscular build and wear XL for shirts and Large for shorts/pants. Both parts of this set are large. I would say it's the size of loose pajamas. The bottoms are particularly comfortable and cover the length of my legs just above the floor (I wear size 30 pants). The top is made of a thicker material than the pants and appears wider than the normal size. However, it still fits well and my hands reach my wrists without being too baggy. I have 34 lengths on my hands. Basically, I like the pants. I gave 4 stars because the upper was thicker and not as expensive as the pants.
