Vintage Diane von Frustenberg Shirt

Vintage, retro Diane von Furstenberg button up blouse. Purchased this at a market as a gift for my mom — the sun was setting and I didn’t see the stains (pictured). I don’t trust myself to get them out or dye the shirt without ruining it, so hoping someone else can show this top some much deserved love 💖 It’s tagged as a large but I think it could fit small and medium, as well. For reference, I am just under 5’8” and usually a small or medium in blouses.
