Men don’t wear skirts. It’s just not something that is done. Sure it may make more sense ergonomically than constricting pants, but it’s just something that we men don’t do.
Now, on the other hand, it is extremely manly to wear a kilt, particularly if you are Scottish. But in Utah, they don’t take kindly to your cross dressin’ sinful behavior. It was a lesson one student learned recently, when his principal made him change his clothes after showing up to school in such a man skirt.
The principal has since been forced to apologize, because kilts are not offensive or inappropriate, they just cost a couple hundred dollars for one. They won’t throw in the codpieces, either.
