I interviewed in a Men's Warehouse Botany 500 charcoal gray suit, blue shirt and Rush Limbaugh power tie. The other seven guys were all in blue suits and six of them had red ties. Perhaps my tie did arrive before me but I did get the job. The best advice above is to get a haircut (2-3 days before), look consevative, being a clone is fine but coloring outside the lines is also OK if you are comfortable with it. I was offered a job at American before SWA and wore the same suit but with the standard red tie.
