I know on the old version of the wardrobe, it gave you an option to see all clothing on subeta. On the new version, I'm unable to find anything like it. I seriously loved that feature, because it helped me a lot by planning my avatar out. Is there any websites out there that does this?

On the items tab, if you check the box marked All Items, it should do the same thing. You can also hide CWs or show only CWs. Is this what you're looking for?
