What's the effay way to take a poop?

I mean this in the sense of how to take a shit when you use dressed in a suit and tie, or with other cumbersome clothing? I get that you take your jacket off, but what about a vest? Do you take your tie off or Todd it over your shoulder?
How do you minimize contaminating your clothes?

I'm genuinely curious. Bonus points for answers involving looking cool while pooping.
