Salma Hayek added an unexpected dose of sugar to the ‘Prometheus’ world premiere, held in London last evening.

The actress looked saccharine sweet wearing a lavender Bottega Veneta Fall 2012 dress with purple-sequined embellishments along the waist and sleeves.

Her tailored dress, with its prim collar and Jackie-O vibe, seems a bit out of place for the world premiere of a major action blockbuster.

I wish Salma had reserved this dress for a luncheon or a photocall, as I do love this light purple hue on her olive complexion.

Matchy-matchy purple Bottega Veneta accessories and a sleek bun finish the look.

Thing to be most thankful for on this occasion is the fresh makeup. Whoever was applying her makeup during Cannes was not doing her any favours.
