Is it permissible for a veiled girl to display modest clothing by wearing the outfit, taking a picture of it, and publishing it on the store's page, knowing that most of the buyers are females and only a few are males?

If the attire reveals something of the body that a man is not permitted to look at, or if it is tight, then it is not permissible to work in advertising for this type of hijab. And whoever gives up something for the sake of Allah, Allah will compensate him with something better.
