Following her glamorous date night out at the BAFTAs on Sunday night with Prince William [1], it was back to royal duties for Kate Middleton on Feb. 13, as she stepped out in London (making a serious case for the skirt suit [2]) to attend The Royal Foundation's Mental Health in Education conference at Mercers' Hall.

The conference highlights the work done by Heads Together [3], a charity spearheaded by the Duke and Duchess of Cambridge and the Duke and Duchess of Sussex. In a tweet, Kensington Palace said, "The conference brings together delegates from health and education [4] to discuss what more can be done to tackle mental health issues in schools in support of both pupils and staff." Get a closer look at Kate's appearance ahead.
