This pajama set has a roomy, comfortable fit. Most people find our PJs to be larger than expected. This allows for a comfy fit and room for expected cotton sleepwear shrinkage, which is approximately 1? in width and length. Waist has 3/4? elastic in the back with a drawstring in the front. Pants are full length and button down top is long sleeved. Due to the fact that this item is NOT preshrunk, expect shrinkage of 1" in width and length. Please buy size accordingly. There will be no refunds on returns of washed items!
