The Duchess attended the Queen's Coronation service at Westminster Abbey today, as one of her final engagements before the royal bundle arrives. The entire royal family was in attendance to celebrate her majesty's 60th Anniversary as Queen.

Kate looked positively lovely in one of her favorite designers, Jenny Packham, a light peach, almost nude lace empire-waisted dress. She paired the look with a matching coat by the British designer and a fascinator by Jane Taylor. She wore her LK Bennett nude heels and carried a small neutral clutch.

The Duchess looked happy and healthy -- with a stunning pregnancy glow -- as she arrived to the Abbey this morning alongside her husband and brother-in-law. It is the first time she and William have attended a public event at Westminster Abbey since they were married there just two years ago.

We loved Kate's choice of a simple, classic dress. Empire waistlines are perfect for moms-to-be because they flatter and don't restrict, allowing comfort and style at the same time.
