Land's End Flannel Pajama Sleep Shirt-Size Medium-Button Up

This is a Land's End Sleepshirt that is flannel and a size Medium. It has long sleeves and buttons up. It is 100% Cotton. Laying flat, it measures: Armpit to armpit-21.5" and the length is 36". It is in great condition. Please measure something that fits you laying flat. The length is measured from the shoulder to the bottom hem. I measure the waist laying flat and double that for the waist measurement. This is for both our benefits so there will be no hassle of returns for not fitting. Thank you in advance.
