Surprise: Meghan Markle Wore Kate Middleton's Dress in 2012

Kate Middleton continues to impress us with her impeccable maternity style. Whether she's casual in sneakers or dressed up in classic dresses, her pregnancy looks are always stylish. Of course, her latest outfit is no exception.

Attending a black-tie gala for the Anna Freud National Centre for Children and Families at Kensington Palace on Tuesday, the Duchess of Cambridge showed off her baby bump in Diane von Furstenberg's Zarita Gown ($900). As it turns out, Meghan Markle wore the shorter, navy version of the same dress on the red carpet in 2012. You know what they say: Great minds think alike. As you might have predicted, Middleton's dress is already sold out, but it's a safe bet that it will inspire plenty of holiday looks this season.
