Changing Specific Colours
Open the 2 images (The image that you want to change color in and the image of the target color that you want to achieve)
Do a range of the part/s of the material on the image you wish to vary, I used the pen tool for all my alternatives.
I place a feather radius of one component to the choice.
Now you have only 2 options to colorise the cloth of the model.
1:Hue/Saturation.
2:Match color.
You can try either method here; sometimes one will give a better result than the other, depending on the image
Hue/Saturation:
With your selection active click on the hue/saturation adjustment layer in the layers panel.
Now that you have the hue/saturation dialog box active, try adjusting the sliders until you achieve the color that you are looking for.
Here is my image before and after using Hue/Saturation:
