Vintage light pink midi dress ONE OF A KIND xs

I bought this dress from a boutique in Santa Barbra. It cost be a pretty penny but I was already so in love with it and then when the sales lady told me the dress was over 100 years old, I was sold. It’s in AMAZING vintage condition. No real visible imperfections with the exception of the rainbow ribbon around the end of each short sleeve is coming undone a bit (see photo) The arm holes are very small. Dress is an xs or an xs
