Remember the old optical illusion posters your brother probably had when you were younger? You had to look at them really closely and circles would start spinning or new shapes would appear? Well believe it or not optical illusions are the latest word in fashion?
The celebrity world have been quick to catch on to this trend with Twilight star Kristen Stewart and model Lily Collins both road testing a Herve Leger version and Victoria Beckham and Confessions of a Shopaholic author Sophie Kinsella trying out Alexander McQueen's style.
They moving lines may give you a headache when you look at them but the slimming effects are unrivalled - not that any of these celeb ladies need to worry about that!
The Alexander McQueen dress goes from dark to light inwards with the black sides looking like a shadow and the white middle creating a teeny tiny silhouette.
The Herve Leger dress looks a bit younger as it goes for orange and black instead of white and black. It uses black vertical stripes which widen in the middle, on the waist, creating a slimmer looking middle.

The trick is in the shading, black detail needs to have grey like shadows around it, so it almost looks like the lines are moving. This is what creates the slimming effect.
If the whole magic eye trick is to headache inducing for you stick to dark panels either down the sides of a dress or across your middle, they will have a similar effect. Anything that can make Victoria Beckham look even slimmer has got to work on us normal shaped women!
