Signature Style - Retro Darling

It's rare to see women wearing hats these days, but at one point it was the perfect way to show elegance and personal style. What better way to channel the sweet retro look than by adorning your 'do with a decorative hat? Royals like Kate Middleton have mastered the exquisite accessory (may we refresh your memory with the Royal Wedding's headwear?) while modern fashionistas like Kelly Osbourne and Marissa Miller have also done some trail blazing to bring back the hat.
