Vintage Japanese Turquoise Kimono Robe S

This is a vintage handmade kimono robe. The fabric is in very nice condition except for a hole in the armpits (could just be easily stitched shut) and a small hole on the opening. Both flaws show in the photos. I do not know what type of fabric this is made from. There is no tie. It would best fit an xs to small. Measuring from back side seam to side seam at underarm is 15 1/4" laying flat. Underarm to hem is 31 1/8"
