@Ricardus luckily, I don't have to follow any dress code.
That said, if I were to design a uniform for anything, I think the Christensen knot would be a the top of the list. Especially considering it's very stable, and therefore suitable if you want to keep a tie permanently tied.
@bkhl I am a fan of smaller, tight, perfectly symmetrical knots. But that's probably more due to OCD than any fashion sense.
Your pic instantly made me think of the "Straighten that tie!!" moment from that scene.
