Born Women's Fleece Sleepshirt-Size Medium-Button Up

This is a Born Women's Fleece Sleepshirt that is a size Medium. It is a button-up and laying flat, it measures: Armpit to armpit-21.25" and the length is 33.5". It is 95% Polyester and 5% Spandex. It is in good condition. It is very soft. 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.
