Bird and Leaf Celestial Chemise

Bird and Leaf Celestial Chemise, Size Large, NWOT. This luxuriously soft chemise is made of 97% polyester and 3% elastane. It has never been worn, but there is a possible spot on the back as shown in the photo. I say possible because I am unsure if it is a design flaw, and I do not want to wash this new item for fear of harming the fabric. *Please note: I live on an island and have cistern water, which can sometimes alter the coloring of fabric.*
