Might be worthwhile setting up your Downloads folder again, say on your desktop you just make a new Downloads folder. Then, go back to the websites where you got things, and redownload them. Make sure this time that clothing meshes are kept together, and the recolours are kept together, either as just a Clothing Recolours folder, or by creator/site. This time, don't delete the .zip after you've installed the clothing, but keep it safely in a back up folder. As you do this, create a new folder within your current Downloads (in the game) called for example *Redownloaded Files) and put the originals together in that. Once you have redownloaded and reinstalled all the clothing files that you are able to find, look at what remains and see if you really want it, if it is, in fact, a collection of orphans, etc.... and if you are happy that you have all you need, then move the whole of the clothing category from the desktop Downloads into your game and delete the originals.
