Personally, I like to use the departments for looking for specific items for specific types of software. I have posted a link below to show you that the left hand menu changes and has Poser and Daz Studio listed so you can drill into the items made just for Poser, but you can also break them down by what figure you want the clothes to fit.  The example link below is for Clothing models.
