Out on a limb here, but...White or light buff leathers have been used on dress military/military uniforms in several countries-it breaks the monotony of the outfit, and lends to "exclamation point" focus. That, and if you are focused on the decorative aspects, and all of the folk in the unit match, well, it makes them all the "same"-our eyes fill in the blanks. Case and point, English redcoats with white crossbelts.

As long as it's not being worn before Easter or after Labor day, I don't see anything wrong with it...
