Celebs get groomed and glam for cartier polo

A swanky event like the Cartier International Polo calls for sophisticated glamour - not very exciting, but if you don't want to get kicked out of the celebrity area, it's worth sticking to.

Model Amber Le Bon and ex-Spice Girl Geri Halliwell both opted for the smooth and sleek look - that's two more to add to team straight! I think Amber carries off the look best - the denim waistcoat over her cocktail dress hints at a bit of grungy edge, whereas with her bandeau boob tube dress, Geri looks a bit WAG-ish. Styling is so important to the new straight trend - Ms Halliwell just looks overprocessed, whereas Amber looks young and cool.

Also in attendance, Aussie pop star and ex-Neighbours actress, Holly Valance, modelling the kind of effortless texture that only bonafide beach babes can pull off. Socialite Poppy Delevigne opted for similar movement, giving her glamorous red frock a youthful feel.

Paloma Faith is never one to stick to a dress code, but even she looked elegant with loose retro ringlets under her statement hat. I love that neon pink lipstick - just the quirky twist we've come to expect from this fashion maverick!
