ft, you guys, where can I take a look at LGO's 小蛮腰，小胳膊? Have been admiring for so long!

By the way, "shape change" depends on what kind of shape do you want to achieve. I think a lot of the perceived "thickness" is actually your bone structure and not quite possible to change, but then, large bodyframe are not bad-looking! I've got wide hips, big thighs, broad shoulder and everything associated with large body frame, it actually helped a lot because it's so easy to get clothes that fit around here. ;)
