I Shall Display both the outfits -
The First Outfit ( BLACK & RED ) Created by - Nezuki can by thought as an original outfit as however it is only used to make Project Diva Version of the Song.
The Second Outfit ( GREEN & WHITE ) is more commonly seen and used in many videos however, the Creator of the outfit and miku's design is not known . ( If anyone knows it do tell me because so far i haven't been able to find it ). This outfit is NOT used in Project Diva videos.
I hope this clears it all ¯\▁(◔◡◔)▁/¯
