A:
It is permissible for a person
to deal in women's clothing that is permissible for women to wear. However, regarding dealing in women's clothing that is unlawful for them to wear, such as the clothes usually worn by disbelievers, it is not permissible for a Muslim to deal in them. Dealing in such clothing involves cooperation in sin and transgression.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
