ako_(dress)_(blue archive) wiki

I want to ask for some confirmation/feedback before I make a change to ako_(dress)_(blue_archive) wiki (also see ako_(dress)_(blue_archive) official_art post search for reference). That wiki says that the outfit is notable for its plunging_neckline, but from what I can see it is a center_opening rather than plunging neckline.

Plunging neckline wiki specifically says that the tag is for outfits that are fully open above the breasts, but this one does close up into something like turtleneck or a halterneck.

Btw, would you consider it a turtleneck dress or a halter_dress? It looks closer to turtleneck to me, but more posts are tagged as halterneck currently.

I understand how this would be mistaken for a plunging neckline but i would surely say this is a center opening instead. A turtleneck can't also be a plunging neckline, those are mutually exclusive

As for the question of turtleneck vs halterneck, i think it's one of the cases where it's both, akin to the virgin killer sweater
