I purchased this from BUYMA last fall, and it is 100% authentic. I haven't used it much, and I've stored it carefully to prevent it from losing its shape! Also, I wore it for short periods because I didn't want to damage it. I think it's perfect for fall and winter because it's made of felt. I believe it cost around 39,000 yen. I saw the image on the Patou website, but it was sold out, so I think it's valuable! It fits perfectly with a head circumference of 56 cm. It's navy with gold embroidery, which is stylish. If you're interested, please let me know!
