Kate Middleton Looks Chic In Navy At Commemorative Service

What a lady!

On Friday March 13, Kate Middleton joined the Queen and other senior royals to take part in a commemoration service honouring those who lost their lives fighting the war in Afghanistan.

The Duchess of Cambridge arrived at St. Paul's Cathedral with husband, Prince William, and brother-in-law, Prince Harry (all dressed in shades of blue), for the memorial.

The pregnant 33-year-old, who's expecting her second child in April, wore an elegant, navy blue knee-length coat by Beulah London with a matching fascinator.

Catherine styled her long locks into an elegant chignon, revealing a pair of blue earrings similar to her famous sapphire and diamond engagement ring. She finished off the look with a matching necklace, navy suede pumps, and a navy clutch.

Though the occasion was much more sombre than Kate's visit to the "Downton Abbey" set yesterday, we couldn't help but notice a glowing smile on the Duchess' face. But hey, we'd be smiling too that close to our due date!

Can't wait to meet the little Prince or Princess!
