These are 23区 brand 7/10 length pants. They are a dark navy color, making them easy to match with other clothes, and suitable for wear across a long season. Made of a sturdy 98% cotton and 2% polyurethane fabric, the sewing is also meticulous. The original price was around 17,000 yen. I purchased them from the 23区 online shop and wore them a few times, but they are in good condition.
