[This subject has been endorsed by a tie retailer ] When is it okay to wear a (virtually solid medium- or dark) brown tie? Let's assume suit-and-tie (or odd jacket with tie) makes sense for the dress code. Let's also assume (a bit broadly) that brown tie is not 'proper' for interviews, weddings, funerals, and evening wear. How about with a conservative suit, such as double-breasted, three-piece, or navy pinstripe? To an appointment with a new client or an important business meeting? Thoughts are welcome.
