I’ll double-check the source of the second photo, but it looks like the original picture is taken from the back and the second is taken from the front.
Add: Yeah, it’s not the EXACT SAME dress worn to the wedding where the original picture came from, but it is the same design by the same maker.
…Also, THIS is the source the second photo came from and today I learned that the dress actually did drive people insane! Holy fuck! 😭
I’m trying not to think about how old this particular meme format is.
