Royal expert Kate Nicholl says Kate is a "very different woman" than Diana.

Kate doesn't seek to emulate Diana, but she does wear her jewelry and outfits at times.

Kate strives to be her own unique Duchess of Cambridge.

She has succeeded in being her own person in the Royal Family.

Kate works very hard to make her role her own.

Her success is attributed to her carving her own identity in the Royal Family.

Kate is a different woman than Diana, and she has made her own way as a senior royal.
