Vintage flowered robe

Robe is actually vintage. I got it from my grandma, and she assures me it is from the 70s. The flowers look like assorted Daisies. The closure is snaps, topped with possible mother of pearl (hard to tell, but it looks that way. the top snap is missing (the top side), but it would be easy to replace. Pit to pit is 20 inches. The sleeves are just shy of 21 inches long and the length is 39 inches. No visible marks. my grandmother always took extreme care with everything she had. size is 1X, but look at the measurements because I believe it runs smaller than stated size. It is 100% cotton.
