We're obsessed with this colour...

The Duchess of Cambridge made a surprise appearance at Buckingham Palace on Wednesday to attend the annual garden party. Kate Middleton wore a bold coral coat dress for the occasion, from of of her favourite fashion designers, Emilia Wickstead.

The royal added a matching fascinator by Jane Taylor, wearing her brunette locks in a chic bun. Kate finished off the look with a white clutch bag and coral heels, and we can't wait to recreate her look this summer.
