According to the mathematical boffins at Cambridge University, Jessica Alba with her perfect proportions has the ultimate sexy strut.
The academics found that it is the ratio between hips and waist that puts the sway into a woman's walk - and the nearer that ratio is to 0.7, the better.
This ratio provides the body with the right torso strength to produce a more angular swing and bounce to the hips during the walking motion.
Therefore, a woman with a 25in waist and 36in hips would have just the right proportions to carry off a sexy swagger as she walks.
