Flowy dark green LS blouse- L, but fits like an XL

Long sleeve beautiful deep green flowy “silky” blouse. It is so flattering to many sizes (I’m currently a S/XS and could make it work). Size is L on tag, but I think it fits more like an XL IMO from when I wore XL. 100% polyester. It does have pils when you look up close throughout (how I bought it at the store) and a small loose thread here and there you could snip.
