you model it in a 3d modeling program. you can export the figure you're making clothing for, from poser as an .obj file, then import it into a 3d app like wings3d, shade, rhino, or 3dsmax, then start building the clothing piece(s) around the figure. just use the figure as a tailor's dummy (you can't use any portion of the figure as part of the clothing itself if you intend on sharing your clothes with other people). If you're making conforming clothing, you have to divide it into groups, using either poser's grouping tool, or a uv mapping program. the groups have to correspond with the body parts of the figure you're making the clothes for. then you have to create a .cr2 file for the clothing so that you can conform it to the figure in poser. You don't have to do this, if you're making dynamic clothing. E.D.
