“The Carrie Diaries,” the highly-anticipated “Sex and the City” prequel, premieres tonight on the CW, and in a smart digital strategy, fans can customize their own virtual bag on Facebook. The Carrie Diaries Purseonalizer app lets users design a purse with digital nail polish as paint just like young Carrie’s bag. We have a feeling the show is going to be a hit among young fashionistas and will inspire some bold style trends, tapping into Millennials' DIY spirit. (Cambio)
