I don't know how to set clothes in Daz Studio

in New Users
Hello. Today I have bought a kit of products for Daz Studio, and I can see them in the library, but they're not in "Wardrobe". They are in "Materials", and when I click twice, nothing happens. Please, I need help. Thanks in advance.

Those are material settings (different colors or patterns, for example) for clothing items. You need to load the clothing item first and then apply the materials to them.
