(Getty Images Europe)more pics » Olivia Palermo  Olivia Palermo was a bright ray of sunshine in Paris as she attended the Giambattista Valli couture show in a cheerful yellow summer dress by Topshop. Rather than borrow a couture dress for the occasion, Olivia bucked the norm and wore a filmy yellow frock from high street chain Topshop. She added shine to her lemony frock with a pair of gold lace-up mule sandals by Giuseppe Zanotti.
