Kate Middleton is a true fall fashion icon. If there's one piece that's become a signature staple in her autumn attire, it's her Blundstone 550 Chelsea Boots - an affordable and versatile boot that I'm also a huge fan of! Princess Kate has styled the Australian-made boots on multiple occasions, including for outdoor outings with her signature skinny jeans, knit sweaters and beloved Barbour wax jacket. I snagged these Kate-approved Chelsea boots years ago after seeing her wear them, and I have to say, they've become a mainstay in my own wardrobe, too.
