I don't have a Bisou, but I do have two Littlefees (a boy and a girl). In sculpt, the only differences between the boy body and girl body is the hip piece, and which set of hands they come with. Everything else is the same. So, if you get one gender and then decide you'd like the other, just swapping clothes would work and no one'd be the wiser. ^.~
Littlefee bodies are pure love! Seriously, these are AWESOME bodies.

My boy has an IslandDoll Kevin head, and Littlefee body. The girl is a Chiwoo, which is available as both a boy and a girl. She doesn't have a face-up yet, since I've been lazy and not gotten around to doing it. Same goes for the Elf-El face-plate that was put on the IslandDoll body. I'd take some more recent shots, but, most of my resins are being kept safe over at PR-Gerry's house while I finish preparing them a place in my studio.
PR-Gerry on the other hand, seems to own all the Littlefees in the world. Okay, maybe she's got more along the lines of a dozen. Pretty sure there's a Bisou somewhere in this shot:
