Clothes for V1 or 2 will not fit V3. Unless you use the V2 to V2 character, it is V3's head on V2's body. Also there is a new hybrid figure in Free Stuff, but you will need V2 in order to decode that one. But there are LOADS of clothes for the regular P4 characters in free stuff. Also try some of the japanese Poser sites, they make clothes mostly for Posette still. Welcome to your new addiction :o)
