No...it's definitely not one of those. The bow is more of a bow and the ribbon is thicker on the bow ties with a distinctive pattern.
I think this may be Barbie, but I'm being tentative because it depends entirely on my memory of my sister's dolls when we were kids. There's a blue hairtie we have which got used for the ponies when we were younger. It looks a lot like yours only it's blue, not pink. I can't remember which of Naynie's dolls it came with, because I basically didn't like dolls - but that may be a place to start.
