Let us look at the Muller-Lyer illusion. Though the line segments in Figure A and Figure B are of the same length, our visual system fools us in believing that the line segment in Figure A (top figure) is smaller than the line segment in Figure B.
Applying this logic to your choice of dresses below:
The dress depicted in Figure 1 has the potential to create a wider waistline than the dress in Figure 2 (in reality the red lines in both Figure 1 and Figure 2 are of equal length). Notice that Figure 1 is like the wider-looking line segment (Figure B) of the Muller-Lyer illusion.
The dress depicted in Figure 3 has the potential to create a slimmer waistline than the dress in Figure 4 (in reality the red lines in both Figure 3 and 4 are of equal length). Notice that Figure 3 is like the smaller-looking line segment (Figure A) of the Muller-Lyer illusion.
Therefore the peplum waist (shown in Figure 1), an iconic look that is in fact back in style, has the potential to create a less flattering silhouette.
Cant virtually everything be explained through human perception and cognition?
