I'm just tagging along to this topic as an older avatar but "mesh newbie" (I just bought my first mesh body within the last week). I also tend to lean "boyish" for my shapes (small butt, small boobs, less hourglass/wasp). Is there any way to reduce/deform/adjust the sway-back spinal curve / forward pelvic tilt / "high heel butt" in female mesh bodies? Or any brand recommendations?
