Yeah, the dress on the website is clearly black and blue. The dress in the picture is clearly white and gold.
This is how it appears to me as well (although I accept that's not the case). The question has split my team pretty much 50/50 here at work with both sides being outraged at the other team; awesome stuff.
Someone on the Reddit thread said that he could see it as blue/black if he took his tablet into a dark room and viewed the image there so I'm going to try that when I get home and see if it makes a difference.
