Duchess Catherine and Prince William still have a few more months before their little one arrives, but Butter London has already created a nail polish to commemorate the mini-monarch. Named "Pitter Patter" to mirror the sound of tiny footsteps soon to be heard all over Buckingham Palace, the shade is an ultra-deep eggplant with dynamic plum shimmer. Ever since Roman Emperors donned the bold hue, purple has been commonly considered a sign of nobility, and we can't think of a more stylish way to celebrate the arrival of the royal baby. This marks the third regal lacquer created by Butter London, with the shimmery violet "No More Waity, Katie," celebrating Will and Kate's engagement, and the lavender steel "Lillibet's Jubilee" to honor Queen Elizabeth's 60 years on the throne.
