I removed kimono and white kimono from some miko posts a moment ago, because, assuming my understanding of Japanese clothing is accurate, what a traditional miko wears is not a kimono. The miko wiki even specifies the outfit being composed of a hakama skirt and white kosode. Except I then realized we don't have a tag for kosodes. A quick check shows that 141 pages of miko are tagged kimono, while the other 638(516 if you remove obvious exceptions Hakurei Reimu and Kochiya Sanae) just aren't tagged at all.
Is there a specific reason we have tags for every type of kimono, but don't have a separate tag for kosodes?
