Very noob question about changing figure material

How can I turn the Genesis 3 figure white, like in http://www.daz3d.com/muscular-women-poses? I just use Daz for art reference and don't know how to do a lot of basic stuff with it, like this. Thanks in advance!

Create a primitive...then select the Surface in the Surface tab. Then File > Save As > Shader Preset...
This will create a basic, untextured 'default' preset. Then you select the figure, all its surfaces and apply the default preset you just created.
If you like a starting point. http://www.sharecg.com/v/81354/ This makes her grey - just change the diffuse to white.
