Graham, Jean Paul Gaultier did go through a "kilt" phase during the 90's, but it was mainly for women. They were pretty much school-girl skirts that were longer.

He designed a lot of Madonna's clothes in the 90's. Now, it's Rocky and Kelly doing her designing. Gaultier designed a fake looking kilt thing for her Drowned World tour, and USA Kilts designed a real kilt for her Re-Invention tour.
