This is a Climate Right Cuddl Duds Long Sleeve Pajama Set that is a size Large. The top has thumb holes at the bottom of the sleeves. Laying flat, it measures: Armpit to armpit-20.5" and the length is 27.5". The bottoms are like leggings and they have elastic at the top. The Waist measures 33" and the Inseam is 28". It is 95% Polyester and 5% Spandex. They are in great condition. Please measure something that fits you laying flat. The length is measured from the shoulder to the bottom hem. I measure pit to pit laying flat for the Armpit to armpit measurement. This is for both our benefits so there will be no hassle of returns for not fitting. Thank you in advance.
