If you are milling around Central on Saturday you may notice shoppers carrying a cotton tote bag emblazoned with strawberries. The bag, which is custom designed by Yves Saint Laurent creative director Stefano Pilati, contains the brand's manifesto published for the new spring/summer season, and shot by Inez van Lamsweerde and Vinoodh Matadin. The publication features Natalia Vodianova in the brand's spring collection, which naturally features dresses decorated with strawberries. Other cities participating in the event include New York, Paris, Berlin and Tokyo.
