When you purchased M3 and V3, you also received "Vicki 3 to Vicki 2" and "Mike 3 to Mike 2" characters, which have the same body shape, proportions, and joint parameters as Victoria 2 and Michael 2.

These special figures can wear the older clothing; however, they don't have any body morphs.

Netherworks has a hybrid figure that combines Victoria 2's body with Victoria 3's head, if you own both versions. It's compatible with Victoria 2's body morphs.
