Salma Hayek in sweet lavender dress London - Arabstoday Salma Hayek was one of the big stars at the “Prometheus” world premiere in London. The actress looked elegant and sweet wearing a lavender Bottega Veneta, Fall 2012 dress, with purple-sequined embellishments around the waist and sleeves. Her tailored dress, with its prim collar had a Jackie Onassis vibe, and we loved this light purple hue against her olive complexion. Matching purple Bottega Veneta accessories and a sleek bun complete the look. She also kept her make-up fresh and minimal.
