Well, this was quicker than I thought!
Here are the textures for Bastila's clothes, meant for the V4 Ultra Bodysuit and HellSing V4 (loinskirt and boots), both available at daz3d.com.
To use them you need Poser 6 or later or Daz|Studio 2 or later. (I created them in D|S, so the surfaces might look a bit different in Poser)
To achieve the looks from the Promos, set
the ChestSpandex-morph in the bodysuit at 100%,
the WaistWidth-morph in the loinskirt to about 5% (it's located in the hip) and
the NoHeels-morph in the boots at 100%.
Figure, clothing, hair and character NOT included -
