PSA: If you want more loli bodies, try adjusting the waistline so it is a bit thicker yet still thin within the smalles height body frame. You should also bias the femoral to tibial ratio in favor of the calf (go negative in the leg ratio option). Finally, hands and feet should not be the smallest they can be. They should be still small, but still a bit larger to make the arm (or leg/calf) thickness look thinner even when operating close to the thinnest option already. This gives them the feel of being teenagers in their "growth spurt," so to speak.
We really need a flat chest option...
