Is it permissible to wear tight trousers (jeans) when going to university, along with covering the head with a scarf?

A woman is not permitted to wear trousers for the following reasons: 1. It involves imitating men, and the Prophet, peace and blessings be upon him, cursed women who imitate men. 2. It describes the body and reveals the size of the limbs, which contradicts the Almighty’s saying: "And not display their adornment except what is apparent thereof." 3. It is considered a custom of the women of the disbelieving Westerners, and the Prophet, peace and blessings be upon him, said: "Whoever imitates a people is one of them."

Loose, wide clothing that covers the 'awrah and prevents fitna is recommended.
