yeah, I've commented the same in that past. I'd assume that it's not the case in real lift. I know Alice looks a bit different in reality. I'm guessing it's more a case of the stylist / photographer / photoshop being a little bit too consistent
I've seen Lily, Trishia, Jessy, Alice and Nana. They're all roughly the same height and all slim, but definitely nothing alike facially. Nana is the most lithe, but also has a couple of quirks. Lily and Trishia are decently better than Jessy and Alice. Nana is very pretty and is good if you get along well.
