Authentic vintage Oriental robe bought in 1966 Japan at no time WORN at least 55 yrs

Authentic vintage Oriental robe that my father bought for my mother when he was stationed in Japan in 1966 ( s55 years ago). She never wore it - just kept it though. I will ask how old and add it to the description. I think the accent flowers are appliqued???? - not sure. No fabric tag ( maybe a stiff cotton?) or care instruction - no size tag either. About 20 from Underarm seam to Underarm seam and about 32.5 from back neck seam to hemline. I am going to guess a small or medium??? There are some white spots on front as shown in photos - don't know if they will come out or not, but still this is an unworn item.I want to call this color a shade of orange - very pretty and cheerful - but the color is just MY GUESS.Colors in photos may appear slightly different because of photography lighting and phone/computer screens, etc superb for everyday use. first-class materials and excellent craftsmanship ensure long-lasting durability.
