Having been emboldened a bit by the fine men of this forum, I have written a formal inquiry to the Human Resources department of my employer, a major pharma company with a very tolerant creedo towards respecting diversity and a dress code that does not make any distinctions between the genders.

Skirts are mentioned in the dress code, and a traditional kilt would seem to fit within the confines of the dress code if I wear it with kilt hosiery.

"Skirts, split skirts (skorts, culottes) and dresses should be longer than mid-thigh and should be worn with hosiery."

I have sent this to HR pointing out that no gender distinction has been made, sent them a nice picture of the Master, Hamish, looking dashing in a button up shirt with collar and one of his many kilts (as an example of what my ensemble would look like on a handsomer man than I). I've asked for them to confirm that I am reading this dress code correctly and that I should be able to wear a kilt, in a tasteful business-appropriate ensemble, to the office.

I'll let you know how it goes.
