The SEO Consultant Dress Code

What should an SEO consultant wear daily? That is the question posted by randfish at a Search Engine Watch Forum thread he named Dress Codes in SEO. He asks specifically;

In the SEO Business, what do you believe are the dress codes for:

1. Going in to the office? 2. Meeting with a new client? 3. Speaking at a conference/event?

For me, even though I am not an "SEO", its always nice pants and nice button down shirt. Randfish says he goes casual for all but a meeting (2). For meetings, he wears a suit and possibly a tie.
