Before the seventeenth century, most ordinary women in Britain possessed very few clothes made of flax, linen or wool, which were difficult to clean. After 1600, trade with India brought cheap, beautiful and easy-to-maintain Indian chintzes within the reach of many Europeans who could now increase the size of their wardrobes.
Then, during the Industrial Revolution, in the nineteenth century, Britain began the mass manufacture of cotton textiles which it exported to many parts of the world, including India.

Cotton clothes became more accessible to a wider section of people in Europe. By the early twentieth century, artificial fibers made clothes cheaper still and easier to wash and maintain. In the late 1870s, heavy, restrictive underclothes, which had created such a storm in the pages of women’s magazines, were gradually discarded. Clothes got lighter, shorter and simpler.
Yet until 1914, clothes were ankle length, as they had been since the thirteenth century. By 1915, however, the hemline of the skirt rose dramatically to mid-calf.
