What is the ruling on opening a shop that sells women's fabrics used in making jilbabs and traditional clothes, knowing that unveiled women may frequent the shop?

The fundamental principle is the permissibility of selling clothes and similar items that can be used for both lawful and unlawful purposes, except to someone who is known or highly likely to use them for unlawful purposes; in such a case, it is impermissible to sell to them. Based on this, there is no objection to opening a shop for selling women's fabrics, provided that they are not sold to someone who is known or highly likely to use them for an unlawful purpose. However, if the buyer's intention is unknown, there is no objection to selling to them.
