*looks at dolls*
*looks back at question*
So... I've got 7 dolls whose heads are on different bodies to the ones they started with. Of those, 1 has retained their character from the previous body (but not the one they were intended to be), 2 have grown into their characters better, 3 are completely different characters now (one of them has changed gender, too, and another their age), and the last I still don't know who they are (she's actually on her 3rd body now).
I've also recently updated a faceup and redone another to match their character better, and updated another to match their new character. Wigs change quite frequently as I find it hard to find the right one.
These are all characters I've made up, btw, although two are heavily based on characters from a book. One of the reasons I make the characters up is that it's easier to change things according to what feels best.
So yeah, I change my dolls
