Kate Middleton's Latest Outfit Is Even More Proof That Her Closet Is Full of Timeless Styles

While Prince Harry and Meghan Markle were busy introducing the world to Baby Sussex in Windsor, the Duke and Duchess of Cambridge were 250 miles away in Wales, paying a visit to the Caernarfon Coastguard Search and Rescue Helicopter Base. For the occasion, Kate slipped into a smart-casual look that's become something of a trademark of hers.

It's not the first time we've seen Kate step out in this double-breasted Philosophy di Lorenzo blazer; in fact, she loves the classic piece so much she also owns it in blue. When she slips into this old favorite, she invariably teams it with a black turtleneck, a pair of black skinny jeans, and matching suede boots for a sleek look. Back in 2017, when she wore this look to visit an air cadet center, she chose a pair of low block-heeled boots. This time around, the duchess added some extra height in knee-high boots with a much higher heel, finishing the look with her Aspinal of London Mayfair Bag. Take a closer look for yourself ahead, and see why the duchess is so enamored with this wardrobe staple.
