Vintage Blue Paisley Paul Harris Design Skirt

Classic navy paisley skirt with flecks of blues and greens. Fabric doesn’t wrinkle. It is heavier and has more drape than it looks like in the pictures. I usually wear an S or 2/4 and it’s a little loose and long in me. I’m guessing it’s an M or 6/8/10? I can send measurements if that’s helfpul. No signs of wear / age.
