London,
Sept 12: The most popular fashion advice – that vertical stripes
flatter the figure – is a myth, according to a leading perception
expert who says that wearing horizontal lines can actually make a
person look thinner.

Contrary to popular belief, stripes that
run across the body are more slimming than supposedly flattering
vertical stripes, according to the research by Peter Thompson of the
University of York.

The study was based on the Helmholtz square
illusion, created by 19th century scientist Hermann von Helmholtz who
drew two identically sized squares and put vertical stripes on one and
horizontal stripes on the other.

That experiment showed the
square with the horizontal stripes appeared taller and thinner than the
other square, prompting Helmholtz to recommend ladies wore horizontal
stripes to make them look taller.

To reach his conclusion, the
expert asked people to compare more than 200 pairs of pictures of women
wearing horizontally and vertically striped dresses.

He then asked them to say, in each case, which of the two they thought was fatter.

His
experiment revealed that when the two women were the same size, the one
wearing the horizontal-striped dress appeared to people to be the
thinner of the two.

And to make the women appear to be the same size, the one wearing the horizontal stripes had to be six per cent wider.

"We
carried out a number of experiments both with squares and oblongs and
pictures of women wearing horizontal and vertical stripes,” Telegraph
quoted Dr Thompson, as saying.

"Horizontal stripes don''t make
you look fat. The one wearing the vertical stripes looks wider than the
one wearing the horizontal stripes.

"Horizontal stripes, if anything, make you look thinner,” he added.

Dr
Thompson said it was not clear why the visual illusion existed,
although it could be that the horizontal stripes made an image more 3D
and introducing depth could reduce width. (ANI)
