Have you (gasp, the horror) searched Marie Osmond dolls to see what kind of value they have? I know some people are nuts for them but IDK how that translates into pricing.
If it seems that you could sell just the doll and get "enough" back to satisfy you, I'd go for it. I know folks recommend patience, but I have none, ha. And I'd say more folks would keep the doll and lose the accessories over the years, making them harder to come by on their own. You can certainly never say never, but if the price is right and you can offload the doll ... BE ENABLED!!!!
