Tartan has been well documented archaeologically as being produced some 5000 years ago. But that has nothing to do with the kilt, which can only be documented, in any form, to just over 400 years ago. Let's not confuse the two.
This is why I said plausible. From every account I've found, nothing notes a kilt in the form we currently know it. I'm only throwing additional info out there. If we're looking at only 400 years ago, I wonder what would have lead them to start wearing it or even the idea to create it? By the way, Livy was around the 4th century B.C. when the Celts crossed the Po river and were raiding the Etruscan villages.
