Swiss Banks and Control of Clothes.

Came across this article about the Swiss Bank UBS:

I've certainly heard of dress codes and what not, but this is a very strict code - down to the color of your underwear!  What's interesting is the context of the bank's desire to "set the table" of the bank itself in the dress code of the employees.  To quote: "He said the bank would issue a pared-down booklet with more general guidelines on how to impress customers with a polished presence and sense of Swiss precision and decorum."  So the visual appeal of the employees should reflect a sense of pride and decorum?  I buy that - to a degree.  I mean I think part of what you look like creates a visual introduction, much like a street with no tree and cracked sidewalks might indicate it's unsafe.  Improving simply the streets, or washing the graffiti has gone a long way to restore certain places - so might improving the dress code at a place of business.  But what I really want to know, is how did they check for the red underwear?
