Gold and White, or Black and Blue?

Hi! THIS DRESS IS DRIVING ME CRAZY!!! It's clearly white and gold!!!! I really don't get how this can happen! It's so confusing. It's especially aggravating, how only ONE person in my class agrees with me!!
So what color is this dress? I've posted a picture of it below. Please comment on what color you think the dress is until then!

Here's one thing I gotta say though: From now on, the world will be divided into two types of people. Gold and white, and black and blue.
