Leave it to Kate Middleton to brighten up a cold British morning. The Duchess of Cambridge stepped out Thursday looking flawless in a pleated teal dress by Emilia Wickstead for an official visit to the Action on Addiction Center for addiction treatment studies in Warminster. The stylish royal paired the long sleeved dress with a pair of modest black pumps and a black clutch.

Not long after, Middleton winterized her look by adding a sleek houndstooth wrap coat by Reiss to her ensemble.

This marks the third time Middleton has stepped out this week for an event—on Tuesday night, she made a dazzling appearance at the Diplomatic Reception at Buckingham Palace where she donned a sparkling diamond-and-pearl tiara, and yesterday she debuted her freshly trimmed tresses at a charity event with Prince William.
