Kate Middleton is not going to like this when she hears it. Even though she is considered a style icon for millions of her fans from around the world, not everyone is impressed with her fashion choices. In fact, she was recently called an 'incorrigible frump' and someone who has 'style kryptonite' by her critics.

According to the Daily Mail on Saturday, the Duchess is being slammed for being someone who can't pick out her clothes for herself, as insiders say that she's not as confident about her choices as one would think.

Writer Sarah Vine didn't hold back when she wrote, "Kate is, quite simply, style kryptonite. Of course, her innate wholesomeness is part of the Duchess's appeal, and no one wants the wife of a future king to be an air-headed fashion obsessive. Seriously, you could put that girl in Versace's infamous safety pin dress - as worn by Liz Hurley - and she'd still make it look frumpy."

Additionally, Vine thinks the Duchess is "unsure of herself" by explaining, "It's as though - whatever she wears - she is anxiously trying to preserve the image of the jolly, dimple-cheeked university undergraduate she was when they first met, all pussy-bows and Boden, fearful still, perhaps, that if she deviates from a tried-and-tested formula he might once more turn his back on her as he did at the start of their relationship. But things are different now. She's earned her place in the Royal Family. It's time to exorcise the ghost of Waity Katie."

She added, "So, Kate, please. Stop it now with the schoolgirl hair, the submissive air and the stiff standing on ceremony....Otherwise - however stylish the designs you wear - you'll only have yourself to blame if you go down in history as the Duchess of Drab."
