Lederhosen, Plattlerhosen, etc. - difference?

Inspired by a current TV ad, and frustrated by trying to find definitions on Google, I ask if anyone can explain just what is meant by the following terms, specifically what are the differences between these types of pants:

Lederhosen

Bundhosen

Plattlerhosen

Gauplattlerhosen

Thanks, smiling bandit, but I saw that site, and while it has illustrations, it doesn’t define the terms. I wasn’t able to get a clear idea of the differences just from looking at the pictures.

Me either. Wiki points out that lederhosen are the ones with the drop front, but there are no articles on either bundhosen or plattlerhosen, and as to a handy website explicating the differences, my google fu is unable to turn up anything. Can it be that the Internet has failed us at last, and no plattlerhosen geek, bundhosen nerd, or lederhosen aficionado out there has taken the trouble to make a web page in oversize fonts lecturing us all on the vital differences between the three? Be a first, then.

I don’t know much about traditional Bavarian or Austrian clothing because I’m from the wrong part of Germany but perhaps I can help with a few general things.

That simply means “leather pants” and it could be any style. Most of the time (especially abroad) it refers to some traditional style but it’s still a very generic term.

Those are pants that are closed below the knee. In general the word can apply to pants made of any material. In this context it’s one major subtype of “Lederhosen.” Depending on the region it’s either the only traditional type or - if there are others - the more formal type.
The less formal alternative is shorter (above the knee) and not really closed at the bottom.

I don’t know but this page has some explanation.

Thanks, kellner, that helps with the first two terms. I also saw the page you linked, but was set back by the use of unfamiliar words (plattl, Schuhplatteln) and direct contradiction (regarding embroidery on the legs) with the photos on the site that smiling bandit linked.

Anyone have further info on Plattlerhosen and Gauplattlerhosen?

That’s a type of traditional dance. There are different variants but the defining characteristic is that you slap your thighs or you shoes (“Schuh”.) (Youtube)
