They let a woman in Arkansas serve on the Whitewater trial and she wore her Feddie uniform EVERYDAY to trial. She also wears her "pajamas" to work everyday too (see Trekkies & Trekkies 2).

So, a kilt should be no problem. Now, if you want to get out of it...and who doesn't...wear the complete Mel Gibson "Braveheart" outfit w/ blue facepaint.
