I am incredibly sorry, for I have sinned. I have tagged about 40 individual works (will post some of them soon), and then mashed the tags together. After that, I added character tags (hopefully only 3 characters miss their tags, and I have no clue who would go through the hell of matching tags and adding the missing ones). Aaand then I just posted this. The main problem (apart from the 4 characters) is legwear and footwear, as most of it is obscured in here, but could be seen in the original works. So there are some waste tags, probably. Also, some colors are likely missing too. aqua_skirt wasn't here, so I added it, but there's definitely some more. Again, very sorry for that, I'll try to fix some of this mess later
Contender for record number of characters or tags?
It looks like post #6171519 has this one best for character count by a far margin. It's a very similar format, but I guess it helps to be able to fill all the gaps between people with Pokémon.
