This looks suspicious to me but I am no expert.
The way the tag is sown onto the edge of the scarf doesnt look right to me because it is not perfectly aligned with the edge. The tag itself looks real though. I am also suspicious because of the fringe, it is knotted on and not created from the weft, which does not look right to me. I also feel like all the skulls that arent smudged are all completely uniform, which does not occur on my silk skull scarf. All the skulls on my classic scarf have slight variations from the printing process. Lastly, i couldnt find that scarf of lyst, polyvore, or any other site no matter what search terms i used...
I would wait for someone more knowledgable to really authenticate it but I am suspicious.
