I even tried uninstalling every mod and reinstalling CBBE first to make sure that that was not the problem. I tried installing CBBE, but nothing happened. I realized that the first time I installed a mod requiring CBBE. Thus, if you put an outfit made for say, CBBE, on the vanilla/default body, the shape will be CBBE, but the textures will be the vanilla body, and due to the UV map difference, the textures will not line up. A UV map is how the texture (the picture) lines up on the mesh (the object in the game). The only thing the outfit and body share are skin textures.ĬBBE has a different UV map to the vanilla body. That is why you can get vastly different body shapes on the same character, depending on what outfit they are wearing.

The outfit will replace the body, not go on top of it.

Outfits in games do not work the same was as in 'real life'. The most popular is CBBE, and most outfit mods are made for it. You haven't installed the required body mod for the outfit mod(s) you've installed.
