RED ALERT: “Strawberry totes, forever” could be Stefano Pilati’s latest anthem. In select fashion capitals, the first 2,000 recipients of the designer’s latest “Manifest” fashion catalogue for Yves Saint Laurent will get theirs tucked into a cotton tote in the strawberry print emblematic in YSL’s spring-summer collection. Roughly half a million copies of the catalogue will be distributed on the streets of Paris, London, Milan, Tokyo, Hong Kong and Berlin on Feb. 20, with New Yorkers getting first dibs during fashion week on Feb. 16. Adding a viral social networking component, YSL will also post three short videos on the making of the catalogue on its YouTube channel, Facebook page and the Yslmanifesto.com Web site, starting this week. The 50-second spots chronicle model Natalia Vodianova going through her paces to achieve each photo before the camera of Inez van Lamsweerde and Vinoodh Matadin.
