I purchased this about two years ago at the United Arrows department store for around 18,000 yen. I'm selling it because I have too many similar items and I don't wear suits as often anymore. I used to wear it with suits, but it's also easy to match with casual wear. It's made of 100% polyester and has a slinky feel. It can be worn in any season except for the peak of summer. It's a blouse and opens with buttons on the front. Width: 50 cm Length: 63 cm Sleeve length: 55 cm Please forgive any discrepancies as these are amateur measurements.
