Should I wear a suit & tie for the first day of work at an accounting firm? I suspect most SFers will say yes, however, I'm having second thoughts. The normal dress code is somewhere between business casual and professional, and specifically mentions blazers, dress shirts and polo shirts as acceptable. Does not mention suits and ties. Some of my friends at other firms were told not to wear suits by their recruiters. If not suit & tie, I was also considering suit without tie, or blazer with or without tie. I'm pretty set on wearing a jacket.
