Monster High Doll Abbey Bominable 2011 Skull Shores, CHECK CONDITIONS

The doll apparently from what I have been able to see online has her entire outfit including her hat, the problem is those places where it has turned yellowish, I have seen some others with this same problem, I don't know if it is something common.
This sale is solely and exclusively for the doll and her outfit,no other accessories beyond what may appear in the photos
Please check every single picture before any purchase any other questions feel free to contact me thank you
