Is there any way I can add a container to armor or clothing? My goal is to have a separate container on my pc so I can sort things from my inventory to said container so I can bring to sell at stores. If so my ultimate goal is to create a backpack type mod that I can wear and also give to npc's if needed.

Thank you

There is a back pack mod on the Nexus that does just this.

Like this one:

There are a couple of pages of backpacks so do a search for the others that may or may not do the same thing. Anyway, see how they did the mod, then use those ideas to make your own. Note, if you publish this, give credit to the mod you gained inspiration from. You may also want to get the original mod authors permission, but these kinds of mods have been around since Morrowind.
