How can I make a cycles material like white cotton material for a doctors coat? 3[]4[]5I am very new to blender and am currently on a very steep learning curve. I am trying to make a nice white coat material. I have managed to make nice materials in other colours. But whenever I use a white colour they tend to come out grey. Above is my current node set up (from a youtube tutorial). 

Could somebody help me out with this? 

Thanks!
The velvet shader often results in darker colors, so for creating a cotton material I would stay away from that. Here is a node setup for a simple cotton fabric:
