Beneath the jacket, men often wear a "Ruqun," which is a long shirt-like garment that is worn as an inner layer. The Ruqun typically has a mandarin collar and is fastened with silk or cloth buttons along the front. The sleeves of the Ruqun are usually narrower than those of the jacket, and they may be visible below the wide sleeves of the jacket, adding to the layered look of Hanfu. Another important component of Hanfu for men is the "Pifeng," which is a wide sash or belt that is worn around the waist to cinch the garment and give it shape. The Pifeng is often made from silk and can be plain or embroidered, adding to the overall aesthetic of the outfit.
