This is a pajama set, in soft cotton muslin fabric, brand new. It was purchased from the fleece company and it turns out their sizing is way off. This is supposed to be a women’s medium but it’s more like an extra small or even a kids size. Otherwise they are lovely pajamas. pants inseam is 23 inches sleeve is 18 inches long and the chest measurement is 18 inches across the pants have elastic waist. I am 5‘5inches and 155 pounds I can just barely button the front and the pants are very tight in the hip area for me not the way I want my pajamas fitting so I thought somebody smaller could enjoy these lovely pajamas
