I'm giving these two tags. They have no official names, and their Pixiv tags are basically "that girl with the jacket" (jaketto no ano ko) and "that girl with the label" (reeberu no ano ko), so either way it's going to be long-winded. This artist likes to refer to them as "jacketko" and "labelko", but I personally find that too silly, even if it is accurately what the fandom calls them.
I'm tagging them with their translated nicknames. If enough people object to that, I'll change their tags to their Japanese nicknames. Wouldn't be a lot of work. There aren't many pictures of the DiPPs, so fully tagging everything they've ever been in was easy enough.
I think our usual naming convention would be something like jacket_girl_(dipp) and label_girl_(dipp). Kind of like ahoge_girl_(23) and dark-skinned_girl_(23), which used to be real_xxiii's_ahoge_girl and real_xxiii's_dark-skinned_girl.
