cloth textures etc for clothing

Hi all,
Im busy making clothes for my toons, some are turning out very well, but I am having a terrible time getting the cloth to look right. its all flat and all one color. The clothes that came bundled with akehuman, seem to have great fabric looks to them, some of which I suspect are photographs modified to fit (no idea how).
can someone point me in the right directions?

Please help.

I didn't find the right solution from the Internet.
