Women’s short sleeve button up blouse

From the vintage brand Panther. Gently used yes barely visible snags throughout. Vintage fabric covered buttons. Size and fabric content labels have been removed please see measurements. My guess would be it’s made of polyester. I wear a large in women’s tops and this fits me perfectly. The last 3 pics are to demonstrate sheerness. The Covid test box isn’t included 😊 Thanks for checking out my closet, please feel free to ask questions.
