I still can't get over the fact that for episode 9, on every other route, Jill gets sexy Honey-Bee outfit. But for her route? BANANA!
I didn't care for it, but peeling it back to get to all that Jilly Juiciness was very satisfying.
DPC's explanation for the Banana costume if you care.
I love the contrast of it compared to most of the other girls' costumes. Like MC says, before meeting Jill at the party, everyone's dressed hot and sexy. There's this stereotype about how girls have to dress hot and sexy for Halloween parties, and I like to play on that stereotype. So, BAM! there is Jill dressed as a banana. To me, it showcases her personality, humor, and spirit. It's one of my overall favorite costumes. I know you didn't ask, but as for her bee costume, it was a bit spicier to make players feel like they missed out on her by not being on her branch. Evil, I know, but the episode was called Vixens, after all.
TL/DR (my translation) - Fuck You.
