>>15658618La+: Meme outfit but the manga panel patterns are quite nice. Looks like she'd trip up easily.
Lui: Not a fan of the colour despite it complimenting her eyes. The corset was an interesting touch and her hairstyle makes her look cute but mature. Ganmo got a whole outfit to go along with her.
Koyori: Top cute. Reminiscent of Towa and Watame from last year. Booties coupled with a skirt and fluffy part for maximum GFE.
Chloe: Glamorous sex worker, lots of exposed skin and red makeup to further accentuate her eyes and blush. Heart eyes and loose sarashi for optimal wallet and cock milking. The pattern work on her kimono is so nice I want it as my bedroom wallpaper.
Iroha: Extremely homely, rural look. The twin tails make her look kind of childish and the outfit as a whole shows how slender she really is. She had lots of cute accessories to go with it.
Nene: Love letter from her mama. Incorporates elements from Nene's own design and mama's concept art. Arguably the most modern of the outfits with translucent socks and almost victorian like frills on her silky shawl.
None of them beat last year's designs IMO but that maybe because I'm not as familiar with 6th gen as I am with 4 & 5.
