Kate Middleton recently wore this classic boot style

Kate Middleton is regarded as a fashion icon. She's been dressed elegantly for over a decade, and her looks keep getting better. Countless people, royal and otherwise, look to the Duchess of Cambridge for classic fashion inspiration regularly, just as Princess Diana did before her. As an example, Kate just served up another look for the record books, and you should be taking notes yet again.

On January 26, Middleton paid a visit to the London office of Shout, the mental health service she founded with Prince William, Prince Harry, and Meghan Markle.

She wore a cheetah print midi dress with buttons down the front, a bow at the neck, also a thick black belt around her waist for the occasion. Aside from her famous sapphire engagement ring, her only piece of jewelry was a pair of trendy twist gold hoop earrings. When we first saw the outfit, our attention was drawn to Middleton's feet because she was wearing a perfect pair of boots.

Tall black boots, like the Duchess, never go out of style. They can be done in various ways, such as with a square toe, a block heel, or leather material. 

Although Kate's exact boots are no longer available, we found six lookalikes for under $200 at Nordstrom, Nordstrom Rack, and Amazon. To top it all off, prices start at $30. So, what are you holding out for? Get a pair of classic boots like Kate Middleton and you'll be able to wear them for years.
