Whilst everyone in America pranced around in their red, white and blue in celebration of the Fourth of July yesterday, the lovely ladies in Paris dressed to the nines for the kickoff of 2011/2012 Autumn/Winter Haute Couture Week. It looks like everywhere across the globe people are celebrating summertime weather in bright colours and sundresses, and it seems that yellow is the colour du jour. Take Olivia Palermo and heiress Eugenie Niarchos for example. They were spotted front row at the Giambatista Valli show donning yellow frocks while the models at Christian Dior walked around in yellow on their feet. What a sunny shade to beat the heat. What yellow garments do you own for this season?
