Shirts
They wear only one unlined shirt for four seasons. Usually in light or dark blue, the shirts bottom around waist with a side-slit. The young men love slim sleeves while the elderly prefer looser ones. On splendid shirts such as those worn by men in Tianba, the hem of cuff and list are often seen with overlapped decorated patterns. And there are also shirts made of fashion machine-made cloth with dyed patterns, or even colorful satin, as opposed to local handmade cotton cloth.
