Not surprised that Maimai's outfits are pretty damn fabulous. It's also good as a "set" of outfits. None are identical but still cohesive. The length of Haruna's skirt kind of bothers me but I understand it as fashion choice.
I really liked this batch of outfits for the most part. Ayumi especially stood out to me, both in the way she looked and with her tossing her hair around. It's always fun to watch performances of that song.
