Kate looked radiant in a cornflower blue polka dot dress by British designer Jenny Packham, which sparked memories of when Princess Diana walked out of the Lindo Wing in a similar printed dress, cradling baby Prince William. Reality TV star Khloé was quick to pick up on this, posting a picture to Instagram that showed the similarites between the two outfits. "How phenomenal is this picture! Awww #PolkaDotPerfection," she captioned the touching snap.
