the hood may be visible enough to identify the garment, but if the hood isn't particularly obvious it should not be tagged.
ok, so we should use the hood tag only if it's 'thick' enough or inflated or the 'loop' or 'hole' for the face is visible, right? sounds reasonable.
-1. Hoodies are defined as the sweatshirt variety. Aliasing would remove the subconscious word association.
nothing against this but this is not the definition danbooru is using since 2008-07-30 . it's not just a sweatshirt variety but 'any garment with a hood attached'.
i didn't create the hoodie wiki but i would infer that the user wanted an umbrella tag for any garment with a hood. instead of creating a hooded_* for every piece of article, hoodie was used. the word itself is neutral enough and short to type. it's also the oldest in the hood*-variant tags, second only to hood.
hooded_jacket has 370+ posts. hooded_top has 3 posts.
hooded_sweatshirt, hooded_clothes, hooded_cape, hooded_shirt, hooded_scarf, hooded_dress, and hooded_sweater were all used in the past but have 0 post at this very moment. i would assume taggers/gardeners moved them into hoodie instead (and possibly to hooded_jacket too).
i'm not sure why we need hooded_jacket separate unless we want a specialized hooded_* tag for every piece of apparel with hood when their differences are tolerable. i think parka has enough reasons to be independent and warrant it's own tag.
of course, i wouldn't mind if the community want to have hooded_sweater to be independent to hooded_sweatshirt or the later from hooded_jacket.
however, for simplicity's sake, i think we should consider an alias at least to those actively used. i wouldn't mind the direction though, so maybe (modification from above):
create alias hooded_jacket -> hoodie
create alias hoody -> hoodie
create alias hooded_sweatshirt -> hoodie
i'm not 100% sure myself, so counter-arguments and loads of input are very much welcome.
