It has no problem in practical use.
I think that there are a lot of people who see deliberately because it is unusual in Japan.

Japanese sense
National costume = Formal wear

I've just heard that they don't wear underwear witha kilt... I've seen a scottish punk band perform and the singer mooned the crowd and you could see it all (an experience unfortunately etched in my mind). Incidentally I have seen a "Scotland" video from Japan (which was part of a series). In that video in particular the kilt was shown a number of times. One time a man wearing one spun around and you could see his backside a bit.

I know women (at least most of them) wear panties with skirts, but I was honestly under the impression that underwear wasn't supposed to be worn with a kilt!

Kilt - Wikipedia, the free encyclopedia

Once you're on the page, press and hold your CTRL key and then press F. A search bar or window should appear. Then type in underwear or just under and you'll see what I mean.

"Tradition has it that a "true Scotsman" should wear nothing under his kilt"

yes Stephen I actually put up a site also about that.

also we used to do alot of scottish and highland dancing-- and my husband Always wore his shorts.

Well, I'm happy to be educated and I'm glad that people do wear some shorts under there. I'm not trying to knock your husband, but I think I speak for most guys when I say nobody cares to know what's going on down there ;).

Someone correct me if I'm wrong, but "kilts=no underwear" as far as the American perspective goes (I'm from California if that makes a difference).

But yea, I'm pretty excited about the fact that I learned something Scottish on the JapanForum.

Let us know how it goes Scotinthesky!

My family is from Scotland, and my aunt had the wonderful idea of presenting me with a full outfit, including a kilt, as a gift some time back. I've never worn it in public. My relatives still own a large home in Scotland, and I have been thinking of visiting, but I have no doubt that they wouldn't be happy unless I spent some time wearing my kilt during my visit.

I've been to a couple embassy parties where I've seen people wearing kilts, needless to say they attract a lot of attention in Tokyo, even more attention than the Japanese men who you can sometimes see walking around town in mini skirts and fishnet stockings.

Traditionally, the kilt is worn without underwear. A joke that was picked up on, on The Simpsons when Bart attached helium balloons to Groundkeeper Willie's kilt. lol. I think a few people where underwear under the kilt now, just in case a strong breeze blows it up and then your done by the law for indecent exposure. lol.
