[Tag Idea] Costume Tags/Qualifier

This would be for those instances where the cosplay and/or *_(cosplay) tags wouldn't apply, but the character is still wearing a recognizable and standardized costume. Example: post #2648822. In it, the character is not cosplaying as any one character from the Ooarai school, yet she is still wearing their uniform.

My proposed idea would be to have a tag like one of the following:

1. ooarai_school_uniform
2. ooarai_(school_uniform)
3. ooarai_(costume)
...
...

They could be added to posts like the above, and potentially even regular wearers of that uniform.

If you wanted to find all non-members wearing the above uniform, you could search for {ooarai_school_uniform alternate_costume}.

To find only regular wearers you could search for {ooarai_school_uniform -alternate_costume}.

Thoughts?

Edit:

Changed title to test resolution of issue #2913.

Some of these already exist eg. fleur de lapin uniform, ama usa an uniform or rabbit house uniform from GochiUsa, or nudist beach uniform from Kill La Kill. For a school uniform example we already have mitakihara school uniform from Madoka Magica or hogwarts uniform from Harry Potter.

I started the Gochiusa uniform tags, so I pretty much already agree with the idea already. Been thinking something like this for roswaal mansion maid (since there are a number of posts that are not specifically cosplay of Rem or Ram), though it would be of limited usefulness since there aren't really any other maid outfits associated with the copyright (so re:zero maid suffices assuming the latter gets tagged as it's supposed to). With Girls Und Panzer, though, there are many different kinds of school uniforms. I started the UTX school uniform tag, for instance, because otherwise it (particularly being an alternate on non-A-RISE characters) is difficult to search for, being drowned out by the Otonokizaka uniforms.
