Fair point, but I actually like the designs of both Sweet Pea and Boa Marigold, so I think I'll chalk it up to the costume design in this case. I suppose I also might be a bit biased here since I severely disliked the whole Kyuin/Franky/Senor Pink ordeal in that chapter…
And I would agree with you on Kaya. It might have to do with her not being particularly sexualized in any way that she actually got to keep her original bust size.
Good points, and yeah I'm a bit biased against Kyuin for the fangirling over the supposedly manly man fighting and yes the costume was atrocious! Miniskirt with a vaccum on the back and one of the "Mucha Lucha" type of face masks with pigtails …. X___X
Sweet Pea and Marigold had better costume desgins ... and well at least Marigold had the better hairdo
