This is a used, size S, purple, women's wing-collared shirt for men's cosplay. It's rare to find this color and collar style used. I bought it at K-BOOKS, a used cosplay shop in Ikebukuro. These kinds of men's cosplay shirts usually cost over 3,000 yen at specialty shops. The tag was cut off, so the brand is unknown. I wore it once for a home cosplay and then washed it.
