This thread's purpose is the discussion of the recently created alternate_breast_size tag.
Tag for when a character's breast size is depicted notably differently from their canonical size.
If a character's canonical breast size is ambiguous (e.g. Izayoi Sakuya), do not use this tag.
I can see how this tag could be useful under certain restrictions... DanielX21 has currently populated the tag with images of 2 characters.
1. haruka_(pokemon) alternate_breast_size
I don't know much about her, but I read the wiki and some comments:
from the wiki:
Known as May in English versions, where she is noted for being rather well endowed for her age (which is then exaggerated even more in fanarts).
Her breast size is really inconsistent in the anime. I blame QUALITY animation for that though.
So I guess she has more than one consistent breast size in canon material. How do we know what is big or small enough to be tagged?
2. hinanawi_tenshi alternate_breast_size
This case is difficult because we don't know her breast size at all. All we have is this:
post #612361, post #374220, zun's design
How can we determine what is enough for alternate_breast_size if we don't know her breast size. This is the same for the majority of touhou characters, btw. For the characters in th6 and 7, we have at least the heights he gave us in his email, but that's it. I think I can savely claim that none of the characters have breasts the size of their head, which would mean that all 416 pages of touhou copytags:1 large_breasts technically qualify for that tag even though for some, that's their standard breast size in fanon.
Additionally, it is very common for characters to be portrayed physically more developped, appearing like 16+ year old characters in terms of waist-hips-bust sizes to appeal to the viewer when they are canonically younger, such as Evangelion's 14 year old girls or Pokemon's 10 year old cast. These are often not "older enough" for adult.
