100% silk. Approximately 168cm in height, 68cm in裄丈 (distance from the center of the back of the neck to the end of the sleeve), 53cm in sleeve length, 24cm in front width, and 30cm in back width. The color is blue-gray, closer to gray as seen in the second photo. There is a very faint stain on the right collar and the back of the left sleeve, but overall it is in near-new condition. The price will be reduced daily, so please purchase when it reaches your desired amount. I will not respond to price negotiations. I will not accept purchases from overly sensitive or demanding buyers who cannot tolerate slight measurement errors or minor oversights.
