New Bodyshape by SciGuy77

Here is a nude top and bottom from SciGuy77. It is available as default and nondefault.

Some technical info from SG77:

The bottom mesh has 1186 face and 833 verts. The top has 2938/1823. Its PLENTY low enough to use on every Sim in your game. All the LOD's are present too, so she keeps her figure even when you aren't close enough to count arm hair. The waist seams match all the CC you already have installed, and any accessory clothing will work on the body without making any changes. Even though the CC you already have installed will match at the waist seams, it'll still have the same flat butt and generic breasts.The sliders all work perfectly, as long as you don't make them TOO large -- especially the fat morph. Curves are made from triangles, and as those triangles get larger, the edges become more noticeable. The breasts really need more polys than I used in this mesh, but for Sims with normal sized breasts she looks very nice.
