This week we saw Kate Middleton meet Dame Helen Mirren (a.k.a. The Queen) in a recycled red Alexander McQueen dress.

That same dress was worn by none other than Kim Kardashian back in 2011, and first worn by the Duchess of Cambridge in 2012.

Since then, we've been keeping track of which celebrities have copied the mom's classic style and who the Duchess herself has taken fashion inspiration from.

From Kerry Washington to Sarah Jessica Parker, these celebs share one thing in common with Prince George's mum: a timeless and classic sense of style.

Take a look at the Kate copycats (and inspirations) below:
