I found some very nice Kimono videos at Youtube. Not many, though, and some uploaders kind of missed the point. But here's the cream:
A
Kimono show. It's more enjoyable if you turn off the sound.
Gackt in Kimono. Don't know him but I want this one! The coat too, albeit it's a little less traditional looking.
And this is not bad either, a girl at a matsuri. She said it was a Yukata, though. [EDIT: see below]
And the reason I went looking for Kimono videos, A music video by Morning Musume Sakuragumi,
Sakura Mankai. There is a... slight Cuteness Overload warning here, but those Kimonos, Uwaa!! Not the ones in group dance scenes, though. They're nice too, I guess, in a way....
