Real Blender experts may have different methods, but this one is the method I use
This method could be used for the tube dress or for the bandeau bra.
Here is the demonstration with the tube dress. In reality you can buy it in 6 colors. But I only supplied one. To get the others colors, simply do the steps described below ...
After importing the character & clothes into Blender change the material setup like this:
- you may throw away the transparent node and the mix-shader, if there is no transparency (for the bandeau bra this is a bad idea).
- put a MixRGB between texture and shaders, set it to multiply
- add a color input, this is the desired color, set factor to 1
- for displacement add a RGBtoBW and add a math node (it is the simple way, I know )
The picture shows the dress in original white color, a purple color you can also get, when you buy the original and black color. You only have to change the color input and to increase the multiply-value of the displacement when you use a dark color to keep it visible.
The next picture is a demonstration what the bandeau bra looks like when I only use displacement and a red color.
