New research published in the journal [*i-Perception*](https://doi.org/10.1177/20416695261441454) suggests that the way striped clothing affects body shape perception depends heavily on the specific spacing and direction of the lines. While people often believe that vertical stripes always create a taller and thinner look, this study provides evidence that horizontal pencil stripes can actually produce the most slimming effect. The findings offer practical insights into how simple geometric patterns alter our visual judgment of the human figure.
Scientists Tzu-Yu Chen, a PhD candidate at the Graduate School of Design at National Yunlin University of Science and Technology, and Li-Hsun Peng, a retired associate professor at the same university, conducted the study. They wanted to explore conflicting theories about visual perception and clothing patterns. A scientific concept known as the Helmholtz illusion suggests that horizontal lines can make a space, or a person, appear taller and narrower than vertical lines do.
Previous studies testing this illusion on human bodies have yielded highly inconsistent results. Peng noted that the goal was to expand upon basic theories of design. “In the field of design psychology, I wanted to move beyond the traditional binary of ‘horizontal vs. vertical stripes,’” Peng explained.
“Most existing studies focus solely on orientation, but our research demonstrates that the interaction between stripe type and stripe orientation significantly influences visual body perception,” Peng said. “Interestingly, our study also revealed that women tend to be more sensitive to these striped patterns than men when evaluating body image.”
David Mitchell already summed this up in a rant on QI that I cannot provide a link to due to ridiculous rules.

And the picture is of a thinner person. Of course vertical stripes look good on her. But vertical stripes have never been slimming for me. I do agree that horizontal stripes look better on me.
I have always thought that creative use of panels is going to be far better than any combo of stripes.
For example a jacket that has a dark panel on the side and light panels on the front/back, that creates a slimmer profile between the contrasting regions.
My wife has a dress with mismatched stripes set at jarring angles. It acts as camouflage. Your eyes can’t find the edge of the dress because it is so disorienting. She looks stunning in it (she looks stunning in anything)
