The picture is the default that comes from uploading to the sims2 website. To create her I used BodyShop, SimPE, MilkShape, Sims2MeshTool, and PaintShop. Here's a somewhat better version, and my rendition of Lt. Uhura from TOS.
And a quick-ref list to step through the editing process:
1. Create a TEMP mesh to be edited
* Open bodyshop
-Create Parts
-Start New Project
-Create Clothing
Select nearest match
-Export Selected Textures -> MeshYeomanTEMP
-Import To Game -> "TempYeoman" comment
close bodyshop
2. Open SimPE
-File Open -> SavedSims/###_MeshYeomanTEMP.package
-PackedFiles->PropertySet_>Plugins get name: afbodyshortdressboots
-FileClose
3. Create project folder Games&Mods/Sims2/Yeoman
FileOpen -> The Sims 2\TSData\Res\Sims3D\Sims06.package
find name in name map
extract data to folder
repeat for sims05, sims04, sims03
4. New file in SimPE (long index)
packedFiles -> Add ...four <xml?> files from above
SaveAs downloads/MESH_AngleWyrmYeoman04242005.package
Plugins->FixIntegrity
Paste new name and hit update, ok, save.
Extract new copies of cres and shape to project folder
Named modifiedcres, modifiedshape
5. Point temp skin at new mesh
FileOpen SavedSims/###_MeshYeomanTEMP.package
PackedFiles_>Add modifiedcres and modifiedshape
3D ID Reference->Plugins->"Package" popupwindow
DELETE old resourcenode and shape from file editor
Drag resourcenode and shape to file editor
move new ones to top (resource first)
"commit" changes, save
6. FileOpen-> downloads/MESH_AngleWyrmYeoman04242005
Geometric Data Container ->Export body.obj
7. SimPE FileOpen ->downloads/MESH_AngleWyrmYeoman04242005
