2. The resemblance between Lady Diana and The Duchess of Cambridge is uncanny here! On the left, we can see Diana at Buckingham Palace in 1980. Diana was a woman of great beauty, and she could wear almost everything with such style and grace. On the other hand, we have Kate Middleton in Alexander McQueen In Charlottetown, Canada during the Royal Tour of North America in 2011, and she also looked very stylish and elegant.
