Ladies in redWith their dark tresses, it's no surprise that both ladies can equally pull off a vibrant scarlet number as Kate did in this Preen number during her 2016 royal tour of Canada. That same year, Meghan looked radiant on the streets of New York sporting a similar style midi dress.Photo: Getty Images

The stylish royal wore a sheath dress by Matthew Williamson that featured ornate beading and a peplum detail to the 2012 UK premiere of African Cats. Meghan sparkled in London a year later wearing a black dress with gold embellishments to the premiere of The Hunger Games: Catching Fire.Photos: WireImage
