What to dress
A：Tomorrow will be my first day at work, what do you think I should be wearing?
B：Well, if you want to look professional, serious and more conservative, a blue dress, white shirt and not-too-high shoes would be the best choice. But sometimes, very formal clothes will keep you at a distance from your colleagues. It depends on the company’s dress code.
A：Indeed, I found most of the employees dress casually when I went to the interview. Only the manager was in suit and tie and he just came back from a ceremony. It seems that their dress code is not that formal. Probably, I should put on a simple shirt.
B：Whatever you choose, make sure they are neat and clean.
