Scroggs is of course right as far as wear something smart and comfortable and no need to go over the top. However, I think the less experience you have or the more ambitious the job is compared with your current status then the more you should put in the extra effort a la pilotbear. For instance, someone straight out of university going for a sponsorship with BA should be paying attention to all the little details and it will make a difference to the interviewers. Conversely, a man of scroggs experience going for an interview with easyjet or Virgin may be fine in cords and a wooly jumper, especially if it facilitates a relaxed atmosphere.
For the vast majority of cases, a decent suit and tie, hanging 2-3 inches below the bottom of your beer gut will do nicely.
By the way Milt,
"Try to excell and foster the ambition."
I believe you meant excel, although queen's english isn't my first language. Put in a bit more effort and one day you'll go far
