Wash in cold water and hang to dry to make it last for many years.

 This skirt is made with ITY fabric:

ITY Knit Jersey fabric is a soft and stretchy fabric with a full drape and vibrant color. The “ITY” stands for interlock twist yarn, which describes how the fabric is knit with interlocking, twisted yarns. This process, in addition to the 95% polyester and 5% spandex fiber content, allows ITY Knit fabric to stretch 40% vertically, and 20% horizontally. Additionally, ITY Knit Jersey displays noticeably bright and vivid colors, due to the fabrics' polyester make-up taking dyes well. ITY Knit fabric is 0.53 millimeters thick, has a 240 to 320 GSM, and weighs approximately 12 to 13 ounces per linear yard depending on the weight grade of which I usually use 280 to 320 GSM . Furthermore, this medium-weight fabric has an elegant, collapsible drape that forms voluminous pleats when it is hung.
