Do your dolls -male/female/whatever each have a 'default' look?
I have 9 of the big girls now, and each of them has been in different looks and outfits, but each also has a wig/outfit combination that is more or less their default look. It's the one that they come back to when they're done playing, it's the look that seems to represent the actual 'personality' of the doll.
Mariko - the girl in my Avatar, has several different looks, but the two she most commonly comes back to are the blond up-do she has in the picture and a long straight medium brown wig with parted bangs. Her outfits vary tremendously, but her 'default' is probably a white top with a skirt - usually a mini, thigh highs and heels.
I just find that when a new dollieh is taking shape physically, their character is taking shape in my mind also, and once they have arrived, I find an outfit for them that seems to capture who they are. It's not always the first outfit that they wear, but at some point I'll put something on them, and it just fits perfectly for the character.
So what about you? Do your dolliehs have default looks? Or are they more flexible than that?
