Nah, Serena is disguised as Ash. That is cosplay. What you're saying is covered in bullet2 : "The owner is also showed in the post while not wearing that garment."

spoiler free for madoka_magica gurren_lagann and undertale in sample posts.
What I mean is when a character canonly wear that borrowed garment, there'll be a large amount of fanart of that character wearing that garment. To prevent that character flood the pool, I put in "Don't add post when character canonly wears those borrowed garments at some point of the story, unless the garment or the act of lending/borrowing it is in the focus." and expecting posts like post #1555991, post #219014, post #2229995 will be in the pool while post #938387 and post #444729 won't.

If switching this to TAG, I guess that restriction no longer needs.
