Hair today, talk tomorrow. Kate Middleton‘s signature blowout is causing a bit of a stir in London, where women are coming into her hair salon, Richard Ward, and asking for the “Kate,” a source tells PEOPLE. And last month in Wales, she famously topped off a windblown ponytail with a feathered fascinator, which had fashionistas abuzz. Now, new pictures have emerged of Middleton wearing her hair scraped back into a chic, messy bun following lunch at posh London restaurant Mosimann’s with fiancé Prince William and her sister and maid of honor, Pippa. All of these ups and downs beg the question: Which hairstyle best befits a princess bride? Tell us: How do you think Middleton should style her hair for her April 29 wedding?
