How do I put a custom pattern on a material i found in the Substance 3D Assets?

I am trying to reproduce the jockey in the image in 3D. I managed to get her into 3D form, I even got her boots and pants done, I've run into problems trying to get her silks done. I found the fabric jockey silks are made of - the lyrca - and even created the pattern I want with the colors I want, but I cannot figure out how to get that pattern onto the lycra and the lycra into the silks without the squares becoming all distorted. Any help would be MUCH appreciated. Im very new to this and Adobe has been no help at all. Support has disconnected me three times now and never delivered a promised return phone call.
