Black Haired Girl With Big Breasts Reveals Her Jean Denim Shirt And Thong Panties On The Sofa Chair At The Window

It is a characteristic of most indigo denim that only the warp threads are dyed, whereas the weft threads remain plain white. As a result of the warp-faced twill weaving, one side of the textile then shows the blue warp threads and the other side shows the white weft threads. This is why blue jeans are white on the inside. The indigo dyeing process, in which the core of the warp threads remain white, creates denim's fading characteristics, which are unique compared to every other textile.
Etymology and origin
The word "denim" comes from the name of a fabric that was first made in the city of Nîmes, France, by the André family. It was originally called serge de Nîmes but the name was soon shortened to "denim."
