What is wrong with you all. He just asked about attire and clothes. I really do not get it why you are teaching him office machinations and politics before he even joins. Is this the moral fiber and ethical fabric we all possess..? Just shut-up with this pagal/yeda nonsense, and let him be at peace. I still remember my first day at office: -and- I did not walk in with such inclinations and subjective thoughts, nor should anyone. Just wish him luck, tell him his answer, and move on.
