A standardized concert idol uniform for Nijisanji, as seen in Danbooru post #7374894. First introduced in 2021 with the announcement of the Nijisanji 4th Anniversary LIVE 「FANTASIA」 and primarily associated with such large anniversary concerts, though it also gets used at smaller events.
It is mostly white and dark blue/black with gold trim. Each member's version of the uniform is made from one of six top and one of six bottom parts (three each for boys and girls), with a personalized accent color plus some unique elements (e.g. Tsukino Mito's rabbit ear headphones).
