Tomorrow is my first day at work , what do you think I should be wearing ?   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 .   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 car key and simple shirt .   Whatever you choose , make sure they are neat and clean .
