Im attending a funeral tomarrow for a coworker that I knew quite well, and I dont own a black suit. The darkest, most formal thing I have is a dark navy sports jacket that has faint white pinstipes. I dont own a white dress shirt, but I do have a very light silvery grey brioni one, which I was planning to wear with a black tie, black pants and black dress shoes. Ive heard mixed comments about it and ive never been to a funeral before so i dont know what to expect. Does anyone think that this is inappropriate any way?
