I purchased this item this year and wore it once for the entrance ceremony. I only wore it for a few hours. After that, I had it dry cleaned and kept it in a bag. However, when I took it out for the photos, I noticed a slight yellowing on the left shoulder area of the bolero. I've included a close-up of that area in the ninth image, but it might be difficult to see in the picture. It's faint even to the naked eye, so it's more of a "it looks like it might be yellowed" kind of thing, but please refrain from purchasing if you are concerned. I purchased this item for around ￥13000.
