I know probably loads of people have asked you this, so I am sorry to be a bother, but what tutorial did you use to first learn how to create/edit meshes and create clothes? Also, do you always use a base game mesh and edit it?
For hair I used the Basic Hair Meshing tutorial by HystericalParoxysm on Mod The Sims, it's a good tutorial for beginners, but it won't teach you how to use 3D programs (this part should be learned from tutorials made for that program). I can't tell for sure about clothing, I kind of discovered things by myself over the time (clicking all buttons and observing what will happen), lol. For clothing I always use EA bodies for a reference because technically you need to create things as close to the EA as possible to work properly in game. For hair I usually start from scratch as EA hair meshes aren't very detailed to start with.
