Whether she’s being accused of social climbing and ‘sucking up’ to her detractors or being portrayed as the serial snob in MTV’s The City, the ringleted Italian-American ‘princess’ is constantly pelted with nasty remarks.

But it’s screamingly clear to me why people (read: other girls) are so horrible about her – and it’s nothing to do with her personality. Olivia’s just too symmetrical for her own good. Evolutionary theorists claim we’re programmed to favour symmetry in the opposite sex and some suggest perfect symmetry poses more of a subconscious threat to same-gender competitors than just plain gorgeousness.

But whatever your take – is she symmetrically pretty or just pretty symmetrical? – Olivia is positively doll-like in this picture taken at the Old Navy Private Party in New York last week. Her look is soft, sweet and totally modern.

The twists in her hair add interest to the straight centre parting and, pulled in to a bun, the style looks refreshingly low-key. Meanwhile her creamy, polished skin is the perfect foil for those soft, pink lips and gently dramatic eyes.

To get that thick, neat wing of black eyeliner, use a pencil along the lash line first – you can correct any mistakes before tracing over the line with a liquid liner and it adds intensity too. (Try Lancôme Laqueliner in Black, £17.50). Spiky, separated lashes open up your eyes without looking too done. Maybelline’s Lash Stiletto, £7.99, is perfect for this.

A final tip: adding blush to the outside of your apples and sweeping it back towards the temples gives gentle definition to your face as well as a rosy glow.
