Double Breasted CoatDESCRIPTION NOUSAN 2021 22 Autumn Winter Collection. Double breasted, tight fitting like between jacket and coat. Since it has a back strap, you can tighten the waist a little, so you can make a change when you want to dress neatly. The material is wool woven with thread that looks like a towel and washed to create a nep and rough look. If you look closely, it is herringbone, not only a rough texture but also a fine texture.
