No matter what's happening in their personal lives, Meghan Markle and Kate Middleton can agree on one thing: skinny jeans look great with riding boots. A few weeks ago, the Duchess of Sussex took to Instagram, sharing a sweet video of her family having fun at a pumpkin patch. Eagle-eyed fashion fans quickly clocked her CO Leather Riding Boots, which she styled over a slim pair of pants. The outfit formula is one that Middleton has relied on for over two decades, often breaking out her own brown Penelope Chilvers boots and rocking them with tried-and-true denim.
