Clothes materials

I bought "Formal MEGA Wardrobe" for G8F.
The clothes are weird colors. This blouse should be white but it looks gray.
Is there some tutorial where can I learn surfaces management?
Some suggestion for this example? Thanks.

Have you tried to do an actual render?
The preview is somewhat limited to how things will look rendered.
To add.
Sickleyield has some nice tutorials, e.g. https://www.deviantart.com/sickleyield/journal/Iray-Surfaces-And-What-They-Mean-519346747
