making a dress thats seamless

Does anyone know how to make the textures of the top and pants part of a dress seamless.
Ive noticed it always looks very obvious. Im using Gimp, is there a method of blending them?

There's no simple way to do it, Shep, but that's what the grid on the templates is for. Each stiny gird square corresponds to the same grid square on the other side of the seam. If you're matching details between the upper body and a skirt, the grid squares don't correspond, but the templates have colored vertical hash marks that line up with the same color marks on the skirt template, and the horizontal purple line on the upper body template is where the top of the skirt is.
