How exactly does Helena Christensen do it? Not only does she look drop-dead gorgeous at 40, but she still manages to be the most fashion-forward star in the room thanks to her endless array of eclectic ensembles. Take Helena’s cool Thakoon rose dress teamed with a classic bow belt and clashing shoes – it's a wild, kooky ensemble that's bang on trend. The frock may come in at a steep £1,100 but if you want a timeless piece that will ensure you belle of the ball status, this is the  frock for you. The Giambattista Valli wide bow belt and cute red shoes add a hit of old school glamour (and can be worn with many an outfit).
