White polka dots

Setting trends wherever she glides, the Duchess of Cambridge, aka Kate Middleton, didn't let a small thing like childbirth get in the way of her impeccable style.Stepping out of St Mary's Hospital in London today clutching the most talked-about accessory of the week (HRH the Prince of Cambridge), there was no fashion rest for Kate as she introduced her new son to the world wearing a simple-but-chic Jenny Packham sky blue sundress with white polka dots.Coincidentally - or perhaps not - back in 1982 another familiar scene unfolded, when a young princess introduced her new baby boy to the waiting media also wearing a white polka-dotted frock.With a distinct 80's influence, Princess Diana rocked a turquoise blue dress embellished with white spots, a white collar, and terribly unfashionable stockings.Given Kate's nod to Diana's post-pregnancy style and her ability to sell out styles in the blink of an eye, it's easy to say white polka dots are the next big trend on fashion's fickle radar.
