Altar'd State Black Lace Overlay A-Line Dress-Size Medium-Back Zip

This is a Women's pretty Altar'd State Black Lace Overlay Dress that is a size Medium. It is 55% Nylon and 45% Cotton. Laying flat, it measures: Armpit to armpit-17" and the length is 42". It zips in the back and is lined. 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.
