Islam encourages the Muslim to utilize his talents and God-given gifts in the best possible way. Part of using his talent in obeying Allah is to avoid using it in an unlawful way. Thus, every muslim is permitted and even encouraged by Islam to use their talent as a fashion designer but they should also encourage that which is morally acceptable and avoid that which is immoral.
Sheikh Muhammad Al-Mukhtar Al-Shinqiti, Director of the Islamic Center of South Plains, Lubbock, Texas, states: The way we thank Allah for the talent He gave us is to use it properly according to His teachings. People of faith, like Prophet Sulaiman (peace and blessings be upon him) attribute everything they have to Allah and understand they are put to a test by Allah, saying: “This is by the grace of my Lord! to test me whether I am grateful or ungrateful! And if any is grateful, truly his gratitude is (a gain) for his own soul; but if any is ungrateful, truly my Lord is Free of All Needs, Supreme in Honor.” (An-Naml 27: 40). On the other hand, people who have no faith attribute everything they have to their mind and intelligence. Qarun is an example of this as he said: “This has been given to me because of a certain knowledge which I have.” (Al-Qasas 28:78)
Allah gave us this talent to use it in a way that pleases Allah and shows gratitude to Him. Designing clothes that are not permitted in Islam is not the way we should express gratitude to Allah. It would be advise to use such talents in making or designing Islamic clothing that would be attractive to people and make them like the Islamic style of dress.
