none of the Gen 4 clothes fit Genesis, not even if Genesis has the V4/M4 shape morphs.

you would need the Autofit plug-in, which is really still a beta .( retails at about $100 i believe)

also, as meatsim has said, all movement/special morphs are destroyed by the Autofit progress. also, only relatively tight clothing converts successfully ( in general) shoes and hair are problematic.
