I've noticed lately that the posts of other characters wearing the Sugoi Dekai shirt are a bit inconsistently tagged. There's a few that are tagged with Uzaki Hana (cosplay), although most are simply tagged as Sugoi Dekai.
When should the cosplay tag be used in conjunction with the sugoi dekai tag when other characters are wearing the shirt? Not sure if it should be limited to posts that feature the original shirt such as post #4021015 and post #4010324, or if it should also apply to posts with parodies of the shirt like post #4013215 and post #3996410
I feel like it has become popular enough that most of the posts shouldn't be tagged with Uzaki Hana (cosplay) unless they are wearing her full outfit, just the sugoi dekai tag should be fine in the same vein that we don't tag Hestia (Danmachi) (cosplay) on every rei no himo post.
Yeah, the current situation is... not great. Most posts tagged sugoi dekai that are other characters wearing the shirt are also being tagged uzaki_hana, which clutters her chartag and makes it hard to find the cosplays/parodies too (though if uzaki_hana_(cosplay) were tagged consistently, searching that tag would find those, and uzaki_hana -uzaki_hana_(cosplay) would isolate the actual Uzaki pictures.)
I personally think the shirt is more like meme attire than a cosplay, and would prefer not tagging Uzaki Hana herself with sugoi dekai and not tagging uzaki hana or uzaki-chan_wa_asobitai! on other characters wearing the shirt either. I would also prefer to limit the cosplay tag to images that don't just feature the shirt but Uzaki's entire outfit, mannerisms, or some other clear relation to the Uzaki-chan source material (tbh, at a glance, I don't see a single non-Uzaki image currently in the sugoi_dekai tag that does any of these things.)
But anything that solves the first two searching issues I mentioned would be an improvement.
Edit: However, since Unbreakable bringe up rei_no_himo, I remember making an argument in a forum thread concerning that tag that it was probably too much work to clean up after every random non-wiki-reading Danbooru user who assumes it makes sense to add a tag directly inspired by Hestia to posts of her, and I suppose the same thing is true in this case. The remaining problem then is just that Uzaki's chartag and copyright tag are on a bunch of posts that aren't actually her.
