The item was described as [pure silk/Oshima Tsumugi] at the time of purchase, but I, being a novice, cannot tell. There are no certificates or tags.

For those considering alterations: The actual amount that can be let out will depend on the seams and other factors, so you will need to consult with a professional after purchase. Please consider the above seam allowance measurements as a guideline, and make your purchase at your own discretion. Also, the above seam allowance measurements were taken by the kimono shop at the time of purchase, and I have not verified them myself. I have not found any noticeable flaws, but please understand and accept that this item has been stored and inspected by an amateur. Some basting threads are still attached. *This is not a new item, but a used one. Also, the perception of flaws varies from person to person. Those who are very sensitive or who are looking for a condition similar to new are recommended to purchase from a physical store. Regarding the color, please be aware that there may be differences between the actual item and the images due to the monitor you are using, the location and time of the photography, and the close-up shots.
