The dress on the left is the dress being sold on an online store or something, and on the right is the picture that everyone is going nuts over.
...The one on the left looks nothing like the one on the right. I'm not talking about the colours, everything is clearly different. Shape, sleeves, bolero...
also, I feel like I have to say this: Buzzfeed? Really?
It looks pretty exact to me. The shape is the same, neither have sleeves(the photo to the right has a little jacket thingy, which I assume is sold with the dress, and just isn't in the picture on the right). And, I'll be honest, I don't know what the last word means. But, they look like pretty much the same dress.
Also, this is just where I found the picture, I think a few other sites have found the original dress and pointed out that it's actually black and blue.
Reminds me of the debate about my own hair colour. Tons of people think it's black, but it's actually really dark brown. When I tell people that they're like 'hurr durr no its black' so I have do respond "do you seriously think I don't know what my own hair colour is?"
