Cotton Metal Collarless SHIRTDESCRIPTION ZIGGY CHEN 2020 21 Autumn Winter Collection. This is a stand collar shirt with a modified pattern that expresses a natural wrinkle like vintage wear with a blend of 90% cotton and 10% metal. The V shaped stand up collar gives a feeling of the elements of an oriental folk costume. The hem and the tip of the sleeves have a cut off design and the more you wear it, the more it unravels and changes to a natural texture.
