As a member of the Royal Family, Kate Middleton is expected to follow strict royal rules when it comes to dressing.
The Duchess of Cambridge has been known to adhere to these rules by dressing in a classy manner.

There have also been times when she was caught unawares by paparazzi while enjoying a private moment alone with family.
Below are 18 photos showing the Duchess of Cambridge displaying too much skin.
