Kate Middleton and Prince William marked a fresh start by moving to Forest Lodge, as Adelaide Cottage became "a place of pain," royal biographer Sally Bedell Smith tells PEOPLE.

Today, the duo attended King Charles’ Christmas lunch at Buckingham Palace in coordinated holiday outfits. Princess Kate wore a bright red dress with a white polka-dotted motif by Alessandra Rich, while Charlotte, 10, opted for a velvet maroon dress with a collar.

The Princess of Wales rewore a red polka-dot Alessandra Rich dress that she first sported for an appearance on the BBC’s “A Berry Royal Christmas.”

Kate Middleton is reportedly "stepping up" with royal duties, including making major decisions about the futures of certain royals, in a bid to "streamline" the Royal Family.

A basic black bag is always a safe bet, but we try to encourage ourselves to step outside the box, too. Kate Middleton certainly did when she hopped on the suede bag trend in late November, carrying DeMellier’s The Small Hudson style during a visit to the Anna Freud Centre in London.
