that makes her look EVEN thinner
She's modelled a few eye-catching garments in her time, but Victoria Beckham's latest outfit was positively hypnotic.
Only days after stepping out in a 1960's style military outfit, the stick-thin star turned heads again and this time appeared to have achieved an hour-glass figure overnight.
However, it was no more than a trick of the eye - an optical illusion - thanks to the clever use of some black and white horizontal lines.
The £2,500 knee-length dress was a present from her close friend and designer Alexander McQueen.
Again, her choice of attire seems to have been inspired by a bygone era. The dizzying pattern was more reminiscent of the magic-eye puzzles that were all the rage back in the 1990s.
Professor Tom Troscianko, an expert in human vision at Bristol University, said: 'It is a very effective design which is clearly there to give the impression of a minuscule waist.
'The thinner white silhouette running down the middle is ridiculously thin and then it expands at the breasts and hips.
'It's the first time I've seen something like this used on a dress but it looks like it is simply a case of clever shading.'
