I would add to this that it might be wise to wait until you get there and are on the job before buying too many things, so you can take a look at what others are wearing, in order to get your bearings.

There is a difference between being dressed correctly and being dressed appropriately. It is possible that you could follow the best advice in the world and show up looking very out of place for the situation in which you find yourself. (And at the Bush White House, who knows.... Cowboy boots?)
