Kate Middleton loves this shirt so much that she has it in at least three versions

Duchess Kate Middleton is a bit of a fashion icon, but even a royal needs a go-to outfit.

Sleuths at “The Daily Mail” noticed that the Duchess of Cambridge has three versions of essentially the same navy-and-white-striped shirt, and wears them frequently. It’s a casual, sporty outfit that nonetheless looks very put together — not bad for the royal version of a hoodie and jeans.

Middleton wore the first of her three shirts -- this one a 'Tippi' from J Crew -- at the Olympic Village during the 2012 London Games.

She wore it again while keeping an eye on Prince George during a polo match at Cirencester Park in June of 2014.
