Kryptozoid
There are some very targetted morphs, depending on which morph packs you may have acquired (I collect as many morph packs as I can find/afford). In this case, however, the Voluptuous morph was 'hitting' the right areas that I wanted to address. Enlarge breasts slightly. Add a bit of bulk to the thighs and glutes, taper the waist slightly.
There's another morph that you can use to 'dial out' voluptuous breasts from another morph pack, but in this case I think they look fine with the tweak.
One other thing that you can do is adjust the x, y and z scaling of a body part (say pelvis or abdomen lower) to more directly control that direction in a general sense, which is something that I do fairly often. See my recent efforts to dial in the My Cute Cousin characters...
