M4 can wear H4 and Freak 4 clothes.

V4 can wear S4, SF4, A4 and Girl 4 clothes.

If you have the Gen 3 body shapes and clones then you shouldn't be getting much pokethrough when Autofitting Gen 3 clothes. Unless you are using extreme morphs.

You really should try the smoothing modifyer its very very useful.
