Razzle dazzle camouflage!
I’m genuinely surprised so many people are familiar with this.
It’s something talked about in perception courses/classes.
The lines make it difficult for humans and machines to accurately gauge depth perception.
For humans it’s related to mach bands. And the way lateral inhibition works.

Not same pose. Look at the different size gaps between elbows and body.
When they said the same pose, they just mean they are front facing, arms to the side, as opposed to different positions for each dress. It’s pretty darn close. She had to change dresses between shots, so the poses aren’t going to be perfectly identical, but they are close enough to make the point that a person looks different depending on the stripes.
Do you really think that extra half inch of daylight between her arm and body somehow faked the result?
