Several years ago, I recall there being news about one or more US Postal Service employees looking to get kilts authorized for wear as part of their work uniform. It recall that it did not pass at the time, however, I ran into an update, or a claim of an update, via a social media post by Utilikilts:

via https://www.facebook.com/UtilikiltsC...54411603526536 , as posted by them yesterday afternoon:

"If you happen to be a US Postal Employee and would be interested in a Utilikilt that is actually authorized by the Quartermaster's office to carry out your duties - contact the store!"

A few pictures were also posted, along with info on them being a limited run.

I'm not sure of the validity of the claim (I have no insider information to confirm or deny it), but figured I'd post it here, in case anyone was interested, or knew of a USPS worker who might be. :-)
