Janab Mufthi Sahib,
A collective subject is that what should be the correct Islamic dress?
1. Shalwar Kameez
2. Jubbah
Apart from this are the Namaz and Ibadath of those who wear pants shirts not correct? Then what will be the situation of those who live in countries like Europe, America etc and in Pakistan too a lot of people wear pants.

In the name of Allah, the Beneficent, the Merciful
The sacred Shari'a has not made it obligatory to adopt a particular code of dress. However, one dress should be in such a way that certain principles are taken into consideration.
1. Dress should cover the Awra (i.e. private parts, which is from under the navel to the knees for men, and the entire body except the face, hands and feet for women) completely
2. Adornment must remain within the boundaries of Shari'ah
3. Purpose of dressing should not be to showoff or boast
4. The dress should not cause one to feel a sense of pride in one's heart
5. Dress must be approved by the learned and pious scholars

As for pants and shirts, since it is the portrayal of western culture and ethics, and also contravenes the Islamic teachings and principles, it is necessary to refrain from unnecessarily adopting this code of dress. Nonetheless, the Namaz performed in this type of dress in valid with a certain degree of dislike.
And Allah knows best.
