Since this portion of the mod uses the folder system from the "Main File" (aka, "Cowboy Outfit Reworked"), it is 100% recommended to have the "Main File" already installed in your "lml" folder before procedding to do anything else.

If you already done that, then all you have to do is pick any of the folders you want to install (make sure to go inside each one of them to get a preview of what they look like) and extract those folders inside of the "Cowboy Outfit Reworked" folder, replace the files when it asks you to.
