It has to do with our eyes and Color constancy.

Basically The dress is Blue and black , however the lighting in the photo makes it look to some people with different eye perception white and gold.

Color constancy is an example of subjective constancy and a feature of the human color perception system which ensures that the perceived color of objects remains relatively constant under varying illumination conditions.
