I’m having a hard time thinking of garments that would be MORE likely to get caught in machinery than an ~8yd piece of fabric wrapped to include open ends, pleats, flaps and the over the shoulder option. A poncho or cloak is the only thing I can come up with.

And yet there is zero chance of an unfortunate zipper accident when wearing a kilt/skirt. Pant zippers are the leading cause of penile injury.
