Hi,
First of all I would like to recommend that you elaborate a bit more when asking a question so it's unambiguous what the issue is.
With that said: Since you sometimes get it to work I assume you know
how to add them and the problem is that you don't know
which parts to add. For that I recommend
Show Mod Info. Once loaded it will, for each subsequent mod loaded, tell you which types the mod contains. Sometimes mods use counterintuitive/weird types. Gloves might be a body mod for instance - causing understandable confusion when neither adding them as cuffs nor armwear works.
If there are any problems with
how to add them there's a guide a the top of the moreclothing settings file that explains everything you need to know. I hope that helps. If it doesn't please explain in further detail what the problem is.
