Black collared dress, polyester, size 100. - Color: Black - Design: Collared, button-down - Size: 100 - Material: 100% polyester - Outer material: 85% polyester, 15% cotton Thank you for viewing. I purchased this at Nishimatsuya in the summer of 2025 to be worn as mourning attire. I have only worn it for two days, so I believe it is in good condition, although this is based on my own assessment. Thank you.
