So if you have studied it enough you may have worked it out and once you know the answer it's fairly obvious. There are two girls in the photo. They're both looking away from each other and into mirrors, which gives the image a layered effect, and therefore makes it look like there are more than two of them. Lead image via Instagram/Tizzia
