Since Kate Middleton returned from maternity leave in early October, she’s been back to her official royal duties and debuted some new looks in the process.

On Tuesday, the Duchess of Cambridge attended a state banquet at Buckingham Palace wearing a blue mermaid-style gown by Alexander McQueen.

Middleton paired her Cinderella-esque dress with one of her most elegant accessories: the Queen Mary’s Lover’s Knot tiara that was previously owned by Princess Diana. An eye-catching, matching necklace completed the ensemble, which Vogue reported is the same necklace Queen Alexandra wore to her wedding in 1863.

Middleton previously drew comparisons to a Disney princess when she wore a sparkling blue gown in November 2017 that looked very similar to the dress Elsa wore in the movie “Frozen.”

While her title is a duchess – though she is also technically a princess – Middleton looks like she has been taking style cues from Disney princesses.
