This is an haute couture piece by Ms. Hiroko Koshino from about 50 years ago, when she was only taking haute couture orders in Osaka. The price was said to be over 300,000 yen at the time. It is still perfectly wearable. This treasure, featuring a silk material, a design with pin tucks on the collar, and a high-waisted cut, is not something you'd find in ready-to-wear clothing. Each piece was made by repeatedly basting and adjusting to the wearer's body, so I have kept it carefully. I have decided to offer it to someone who appreciates its value and will cherish it. I hope someone studying fashion will take it. If I don't find a buyer, I plan to give it to Ms. Koshino's atelier. The lining has deteriorated over time, but in my amateur opinion, the outer fabric shows no stains or deterioration. It is still perfectly wearable. What do you think?
