When it comes to events in the Royal calendar, for Kate Middleton and co. a coordinating hat is a fashion essential, and the anniversary celebration of the Queen's Coronation at Westminster Abbey was no exception.
Giving us a tried and tested lesson in topping off a formal look, the Duchess of Cambridge opted for the same Jane Taylor hat she wore at last year's Jubilee lunch. Like in 2012, the fan-detail headpiece was carefully coordinated to a lace dress, though this time she swapped Alexander McQueen for a pregnancy-appropriate empire dress by Jenny Packham.
Equally expertly coordinated was leading lady of the day, The Queen. With decades of practice, it's no surprise HRH was elegantly kitted out with a wide-brim hat in the same fabric as her jacquard dress coat. For extra points, it had faux roses attached under brim in a matching shade to her brooch.
More experimental in the millinery stakes was Princess Beatrice who made a controversial choice of hat at the Royal wedding, but clearly wasn't perturbed as she matched her amethyst-hued outfit with a feathered fascinator by Sarah Cant.
Zara Phillips was the most fashion-foward guest of the day with her choice of ornate black Karen Henriksen hat, matched with graphic print shift.
