A small example. There are similar catsuit meshes for both Posette and Vicky, and there is a Spacepilot texture available for the Vicky catsuit, from from DAX 3D. It is possible to re-arrange the Vicky texture to work with the Posette UV mapping. The free texture is sized at 3000x3000. To get the pixel size of the actual mesh surface to be the same, the Posette catsuit template (made with UVmapper), had to be 4050x4050. There's quite a few differences at the edges of the mesh, but the end result was OK.
