Bonjour pink and white button down - tiny stains see photos

Bonjour brand button up / down shirt (women’s according to the button placement) pink and white vertical stripes. 100% cotton, size medium Some small stains through out, as highlighted in the photos - almost all of them are on the back of the shirt. (but maybe you need a new art smock or other lovingly used shirt that you don’t want to feel guilty about staining!) Likely vintage but I’m not sure about the date
