For me its:
Ame>Kiara>Bae>Mumei>Mori>Kronii>Fauna>Ina>Sana>Gura
I genuinely LIKE all of them (Except maybe Gura's), but my autism is going to force me to do a breakdown.
>Ame
This outfit is quite frankly just incredible. Its relatively simple but the color scheme is outstanding, but what really makes it are the hairstyles. Might be my favorite outfit in the entirety of hololive.
>Kiara
Again, the colors are really nice here, but the head really shines. Her hair and face design is really nice, very fitting and she rocks the outfit quite well.
>Bae
Im very conflicted on putting this third and not second. This outfit fits bae perfectly. The hair is great, the colors are great, and Im a big fan of the long socks with nice ZR at the top.
>Mumei
ABSOLUTELY FANTASTIC. The red with the white is a classic pairing, but I really like the pattern style on her white kimono. Also the braid with the short hair and beret is an incredible head design.
>Mori
Moris fits her reeally well. The smoke effects off the side are a cool edition. It has the sex appeal, great high leg. Her hand and arm position are a bit annoying since it seems she cannot put them down, but the mask is cool as well. Great color scheme too.
>Kronii
In terms of pure design I really like the snake motif that the whole outfit has. The nerf she received here is so severe that I have to deduct some points. She looks like the flattest of the group now, which is fucked if you ask me. Cute sperm though.
>Fauna
Honestly was a little let down by how plain it is. I dont really go in for the maid/apron motif so that doesnt add much for me. The extreme bounciness of her hair is a little odd, but i love its design.
>Ina
I think kuroboshi papa and I just dont gel well. The pattern work is really quite masterful, and I have nothing but respect for kuroboshis hard work, but it jsut doesnt really do it for me.
>Sana
Man, I REALLY want to like this one more. Her reveal was great, and I really like all the little things pako added. But man, that fucking PINK. It really is distracting on stream, particularly seeing it here in this collab. The pink is too much, its just garish and distracting. I real shame for me.
>Gura
I just... dont really like it. It has the same color scheme as all of her other clothes, not really any interesting accessories, and such a similar hairstyle to her pase outfit that it might as well be the same. I think its cool and cute that she drew the shrimp on her head, but the rest does almost nothing for me. Its criminal that Gura continues to get done so dirty in the outfit department.
