From the official website: A series made with sustainable materials using recycled yarn. The vintage processing gives a flat fabric a subtle fullness, resulting in a natural look. The moderate stretch and light feel also make it attractive for stress-free wear. The pants have a straight silhouette that falls straight to the hem, but the compact hip area creates a neat, feminine impression. The waist has a clean design without elastic, allowing for a balanced look whether tucked in or out. A basic item that can be widely used from commuting to occasion scenes. The tag has been cut off, but it's a beautiful item that has only been tried on.
