This item is guaranteed authentic, purchased at a PRADA flagship store in Japan this March. Please rest assured. I would prefer not to disclose the specific store receipt details due to my relationship with the staff. Size: 36, Black. Retail price: ¥429,000 I tried on a size 38 at the store, but it didn't fit well, and size 40 was too big. Size 36 was sold out, but the staff member worked hard to get it for me. However, I haven't had a chance to wear it since I bought it in March, at the end of the season. I believe it's a very beautiful item. The collar and cuffs are clean, and of course, the down is not flattened and remains voluminous. There is some slight wear and tear typical of velvet. Accessories: paper bag, garment case, velvet hanger. Sleeve length: 50cm Shoulder width: 47cm Length: 46cm Pit to pit: 54cm Please allow for slight measurement errors as these are amateur measurements. I will ship it carefully without compression. This item has been in someone's possession, so please refrain from purchasing if you are concerned about minor details.
