Kate Middleton Steals The Spotlight In A Sequined ‘Frozen’ Gown At Buckingham Palace Reception

Kate Middleton is an ice princess — in the absolute best way!

The Duchess of Cambridge looked stunning for an evening reception at Buckingham Palace on Tuesday in honor of members of the Diplomatic Corps. The 36-year-old royal channeled Elsa from “Frozen” in an elegant, sequined baby blue gown with the ultimate accessory: the Lover’s Knot tiara that once belonged to Princess Diana.

Kate was on theme for the night alongside both Queen Elizabeth and the Duchess of Cornwall Camilla, who also wore embellished gowns.

Earlier in the day, Kate appeared to be in full holiday swing when she stepped out with Prince William dressed in a festive plaid skirt from Emilia Wickstead and a black Brora cardigan.

The couple got into the Christmas spirit during a celebration for military families at Kensington Palace, which even featured faux snow!
