Philip Treacy made more than 30 hats for guests at Prince William and Kate Middleton's royal wedding, so you know he's well-versed in crafting the perfect finishing touch for any special outfit. Expertly handcrafted from sinamay straw in his London milliner's, this one is embellished with a sweeping buntal ribbon and organdie flower. A swipe of red lipstick will really make the navy and ivory shades pop.
