When the Tartan Army (the name of the travelling supporters of Scotland at international football fixtures) travel, they generally all travel in kilts, as the full things are very heavy, and it's easier to wear them than pack them.

Unsurprisingly, Edinburgh and Glasgow don't generally bat an eye, since they see enough kilts, and they are in Scotland. We've had reports that LGW have insisted that all of the accoutrements (kilts are generally worn with kilt pins and various other chunks of metal, so they don't gap and inadvertently reveal the <ahem> crown jewels) can not be worn on aircraft, requiring an entire aircraft of Tartan Army to have to make their way to check-in to recheck bags. Most Scots know to check their sgian dubhs (the ceremonial daggers worn in the sock as part of the traditional outfit) or get replicas - although a friend had his replica (consisting of a handle and a scabbard and no blade, bought especially for when he was travelling without checking a bag) confiscated at EDI recently - and got an apologetic letter back when he complained about this.

But I suppose it's not too surprising that a US airport is unsure about how to search someone in a kilt. What is extremely surprising is that any government employee would ask such a culturally and racially insensitive question as 'why are you wearing a skirt?' Please god, never let him meet the Tartan Army, as while they are generally good natured, peaceable and law abiding, a question like that would likely see him decked. Does the US government not require any form of diversity training for its employees?
