This mod will give your Sims 4 male sims teen through elder their missing equipment. It will also make the male bottom visible as a clothing choice in CAS - click on Bottoms and clear any filtering options to find it.
The mesh is the same one I used for Sims 3, originally supplied by Rockerduck. It is NOT morphable at this time.
Installation: Download the .package file and put it in your Documents\Electronic Arts\The Sims 4\Mods folder.
Troubleshooting: If you have problems, please explain what happened or didn't happen. Be as detailed as possible. I won't answer posts that just say "It doesn't work."
Update 9/18/14: Modified to not conflict with body hair mods. There should be no conflicts with properly made tops, shoes, or body hair. HOWEVER, any tattoos, skin details, etc that are applied to the side of the lower left hip will show up on the p(Google Censorship)s. Unfortunately my choice of where to map the texture is very limited and this is the best I can do for now.
