In their first public appearance as a married couple Kate Middleton, the Duchess of Cambridge and Prince William stunned on Thursday at the tenth annual Absolute Return for Kids gala dinner in London.

Kate shined in her Jenny Packham gow, covered in intricate, beaded detail and LK Bennet shoes. Kate looked absolutely royal in the tasteful, beige-pink, sheer gown.

Kate paired the ornate gown with simple jewelry and her natural long hair.

How does Kate's elegant gown compare to Lady Gaga's mermaid dress from German T.V.?
