One of the fold is called the Flat Pocket Square, it gives an elegant simple image. It’s used especially with a black suit and a black bowtie. For party or other events it’s used the white silk handkerchief. There is also a fold of one, two or three points. Also in this case the selection of fabrics is really different: silk, wool, cotton.
