Prior to tag gardening, there were a significant number of Yae Miko posts in which her white outfit was mistagged as a kimono, despite the fact that her outfit does not even resemble a kimono to begin with (her outfit lacks the y-shaped opening that is typically seen on the front of kimonos). I'm not sure where the mistagging is stemming from, either because taggers assume her outfit is a kimono just because it is Japanese-themed, or if it's because of taggers arbitrarily taking tags from the Related Tags function (in which Yae is commonly associated with Raiden, who actually wears a kimono)?
Thought I might discuss this with other users for their opinion if they agree that Yae's outfit is not a kimono, meaning that her outfit was mistagged by users.
