How do I know if I found a Monster High doll?

I do thrift store hunting often, and I always keep an eye on the dolls in case something good pops up. The latest interest has been Monster High. I found a doll that looks Monster High, but I'm not sure. She has a clip-in hairpiece: thick, honey-blond wavy hair with a side-part to fall over one eye. The hair beneath is plain painted yellow. Her eyes are hazel-green, more like a porcelain doll's realistic eyes than a normal Monster High barbie style. Lips are glossy light pink, large lower lip. Light blush on the cheeks. She came with heart earrings with a skull and crossbones - skull has a bow. No other clothing to offer any trademarks. She has all the moving wrist/elbow/knee abilities, waist bends and she can do the splits, but her feet are flat like a boy Monster High and they turn at the ankle. She is approximately 27 cm tall. All in all, she looks like a Monster High but she seems too complex to be one of the popular kinds I saw pictured online. Anyone have any ideas? Thanks!
