Which world do you live in, Mr. Khattak?

In Europe & North America, event in multi-nationals, people wear jeans, including female.... I am working in a multinational at Paris, and our CEO (who is a female) wear jeans, let alone, the subordinate staff. Yes, on certain special occasions, like during a meeting with a foreign delegation etc, ppl wear dress paint & shirt with a tie.

A point to be noted, that bus drivers in Europe are required to wear complete suit, with tie
