The "Kilt Police" would walk up to a stranger, interrupt a conversation he is having, to say, "Your kilt is too long!" And he'd probably get some angry words in response, or at least an angry glare.

--

A gentleman would strike up a conversation with the fellow, exchange friendly greetings, and if the moment presented itself, ask, "Is that a new kilt?"

And when the person said, "Well, it's new to me, but it's an older kilt, a friend bought it for me off of ebay."

And the gentleman would say, "It's a really nice kilt, it looks well made. It's a tad long, though. If you were to have one made for you, you'd want to shoot for somewhere between mid-knee and just above the kneecap. I think above the knee is the most comfortable, but that's personal preference."

And perhaps the other fellow might ask, "Do you think this kilt is too long to wear?"

And you might reply, "Well, it does look a bit long, you might try wearing it up a bit higher on your waist and see how that does. If not, I can give you the names of a few people I know who might alter it for you. It's a nice kilt, it would be a shame not to wear it."

See the difference?
