Is the reference for clothing to be found in custom?

The questioner : Regarding the issue of clothing, does what we see some people wearing, such as the turban, the trousers, or what is known as the Pakistani outfit with the shirt, does this belong to the Sunnah itself, or does clothing revert to custom and habit? We ask for a detailed explanation of this issue?

The Shaykh : In Islam, there is no specific uniform or specific clothing for Muslims. This is because we know that the early Muslims, who were Arabs, when they conquered the Islamic lands, and these lands were between Roman or Persian territories, they had their own clothes and their own styles. What was imposed on them, considering they were all Muslims, Arabs and non-Arabs alike, was not a specific Arab Islamic clothing. Rather, they were left to their customs and traditions. However, this wise Lawgiver established some rules for their clothing and styles that must be adhered to in their clothing and styles, and in everything they engage in among themselves. Two rules come to mind from this: the first is to avoid extravagance, waste, and squandering of money in styles and clothing. The Prophet (peace and blessings be upon him) said: Two things are wasteful: squandering of money and arrogance. This is the first condition. The second condition is that the Muslim's clothing and style should not resemble the clothing and styles of the disbelievers. There are many and numerous hadiths regarding this, some of which are the principle and rule, and some are the application of this principle and rule, or a derivation from it. The principle is his saying (peace and blessings be upon him): His saying (peace be upon him): This is the second principle that the Muslim must adhere to in his style and clothing. If he avoids these two matters—extravagance and arrogance on one hand, and imitating the disbelievers on the other—then he may wear whatever he wishes. Whether he wears, for example, a long shirt that goes below the ankles, or a shirt that reaches the knees, or above that, if he is wearing trousers or not, but he wears an abaya, or wears a long shirt, or wraps himself in a garment, he is free to wear what he wants, just as he eats what he wants, within the limits of avoiding extravagance and arrogance on one hand, and imitating the disbelievers on the other.
