Trend Alert: Pastel Dresses - Blake Lively and Michelle Williams

Last week saw a run on pastel flavoured outfits. Everyone was in on the action. And in a hemisphere suffering from a cold snap. But fashion waits for no sun, and so pastels are in, and we get to take advantage right here in the sunny southern hemisphere. Yay us. It all started with Blake Lively who busted out the Valentino beautifully early in the week. Michelle Williams came up quickly from behind in her sublime floral Erdem frock. And you have already seen Michelle Obama do it in J.Crew. The message is clear. Pastels are in and you need to get on board. Now go!
