Praise be to Allaah
There isn't any special material in Islam for wedding cloths. Islamic Sharee'a( Ruling ) is merciful not to place such provisions. However, there are general guidelines like forbidding men from wearing items that are specific to women such natural silk or gold since both degrade manhood. Furthermore; women are forbidden to dress like men. All of this is based on the concern of the Islamic Sharee'a to distinguish between the two sexes since the removal of such distinction is primary causes for corruption and decadence.
