Hot pink button up

This appears to be a handmade button up top, I know it’s vintage but don’t know from what era. It has a super cute eyelet embroidered design, with a Peter Pan collar, and all buttons are still attached. There are no tags on it anywhere, but it fits me so I’d say it’s a large. There are some random spots, maybe from perfume or lotion? Other than that, it’s in great shape! Please ask all questions before purchasing Thanks for looking 💕
