Christian Louboutin When working with a tried-and-tested style, you can always afford to go a little bolder on the details, and Christian Louboutin's 'Cosmo' heels are the perfect example. Classic enough to wear to work, but on-trend enough for evenings out afterwards, this glossy patent-leather pair is trimmed with PVC and has cutouts at the heel. Match your jewelry or eyeshadow to the shiny gold piping.
