These reproduction stockings are suitable to wear with Victorian and Edwardian clothing and are made on antique machines with original patterns.
I wear women's shoesize EU 41, have small feet and regular sized calves and wear them without issue. These stockings will stretch up to men's shoesize 47 and are suitable for those with sturdier calves.
90% cotton, 8% nylon and 2% lycra.
You can wash them by hand or in the washing machine on wool/delicates setting. To keep them looking their best I would dry them on the washingline.
