What is the ruling on going against the prevalent custom of the country in clothing if the country's attire conforms to শরীʿআ (Islamic law) requirements?

Customs, traditions, and norms related to clothing have different rulings:

1. If they conform to Sharia: They are affirmed and should be adopted. 2. If they contradict Sharia: They are not permissible to adopt, as was the case with the idolaters in their adherence to the ways of their forefathers. 3. If they neither conform to nor contradict Sharia (i.e., they are unaddressed): It is legislated to conform to them, based on the Almighty’s saying: (Hold to forgiveness, and enjoin what is right [Al-A'raf: 199]), and because the Prophet, peace and blessings be upon him, conformed to the customs of the Arabs in their clothing as long as they did not contradict Sharia.

It is legislated for the people of each land to wear what is customary among them, and it is disliked to contravene it. It may even become forbidden if it reaches the level of "garment of fame" (libas ash-shuhra), which is clothing a person wears to become famous and distinguish himself from others. The Prophet, peace and blessings be upon him, said: "Whoever wears a garment of fame, Allah will clothe him with a garment of humiliation on the Day of Resurrection." This includes both expensive and humble clothing if the intention behind it is to gain fame.
