It's nice that the wiki entry for wardrobe_error includes a lot of related tags, but I'm still surprised that wardrobe_error isn't an implication whenever those tags are used. The panties_on_head tag, for instance, when added to an image doesn't automatically include the wardrobe_error tag like it should. Someone should fix this soon.
On a small note, I know that the asshat tag refers to a hat being worn on the buttocks, but the word asshat was also often used to refer to the silly heart-shaped hat used on an episode of Code Geass R2 (due to the fact that it looked like a pair of buttocks when seen from above). What would be a good tag for that hat--cupid_day_hat maybe?
