Brilliant in blue! Kate Middleton's post-maternity leave duties just keep on coming, and the latest—the Rugby World Cup 2015 in Twickenham, England, on Friday, Sept. 18—had her donning a gorgeous royal blue coat for the occasion.

The Duchess of Cambridge, 33, who, after giving birth to her second child, Princess Charlotte, in May, modeled the stunning Reiss topper at the event. It was the perfect complement to her sapphire engagement ring, which she sported proudly on her left hand.

For beauty, the Duchess chose an especially rosy makeup palette, including bright pink cheeks, teamed with her signature bouncy blowout, accented by her new bangs (publicly debuted the day before at her first official post-maternity leave event and still going strong at the match).

Of course, the royal beauty wasn't alone! Middleton was joined by her husband of four years, Prince William, who complemented his wife by wearing a navy-blue suit with a printed blue tie. Per usual, the lovebirds were snapped laughing with one another throughout the match, wearing ear-to-ear smiles.

Just a few feet away sat William's brother, Prince Harry, who looked especially handsome thanks to his blue suit and bearded state.
