An Australia based mathematician has come up with a formula to provide women with a fool-proof flattering look, based on a ratio linked to Egyptian pyramids and Leonardo da Vinci's famous painting Mona Lisa.
Mathematics honours graduate Lily Serna's equation for the perfect dress,
skirt or short hemline is the length of a woman's body from shoulder tip added to their heel height and divided by 1.618 which gives an individual 'Golden Number'.
Once the personal golden number has been determined, women need to measure from the shoulder down to see where the golden number and hence their ideal dress length, lies, 'The Australian' reported.
Serna, who was hired by a razor brand to create an illusion of 'perfect pins' - whatever a woman's shape, size or age - drew on ancient principles of beauty, proportion and visual balance.
