I agree with you, but if you measure the width of the dress at the tip of her fingers, the left and right are about 99-100 pixels, while the middle one is 105 pixels wide. Her face in all three images is about 38-39 pixels wide (measured at the earlobe), so that rules out they stretched the entire image slightly. But 5 pixels is significant enough to kind of muddy the validity of the OP’s message since it no longer rules out all but the appearance of the dress. It sadly happens that sometimes effects are exaggerated, even when there is a real effect at play.
