What do you guys wear to work? I usually go to work in jeans and T-shirt. And I grow a mustache and beard. But my cousin is suggesting me to do clean shave and wear formals to work everyday. He says that it'll make a good impression in the workplace, like I take work seriously.

I do get his point because I automatically give more respect to people who come to office in formals. But I don't feel comfortable working in formals. Moreover my workplace is very casual and my manager, TL, VP all wear jeans (even torn) and tee.
