WHAT'S HOT One-piece swimsuits Less tacky than bikinis. Go for 1950s-inspired numbers. Comfortable shoes Forget Gwyneth Paltrow's 7-inch heels; bring back comfy trainers and flats. Pashminas They are having a revival but they were never 'out' in Style Meter's books. Bring the trend up to the minute by wearing it wrapped around the neck with the ends loose on either side. Tailored waistcoats Excellent for layering or to be worn alone on hotter days. WHAT'S NOT Corsages Sex and the City is back but the trend it once launched is not. Fringe bags We weren't impressed when Prada did them, so why would we be convinced now? The hip-hop look Don't even try it in clubs unless you want to be asked to leave. Tiered prom dresses So Lily Allen, so 2007.
