Kate's Middleton's most expensive £7,300 dress that she's only worn twice

The Princess of Wales is known all over the world for her incredible sense of style and her unwavering dedication to her many important charities and patronages.

The sizeable impact that she has had on the fashion industry alone has been dubbed as "The Kate Effect", as whatever she appears in typically sells out in minutes.

Kate continues to wow the crowds at her public appearances. Whether she is appearing in a floor length gold Jenny Packham gown for a glittering film premiere, or arriving in London to hand out a fashion award, the Princess has her public image down to a tee.

While Kate has brought us many iconic and unforgettable looks, one of them has an incredibly large price tag and you certainly won't guess which dress it is.
