Whatever you may think of royalty I haven't met a person who doesn't think Kate Middleton isn't beautiful, sophisticated and a bit of a style icon. Her style is elegant, classic and often quite basic.
Her clothes are constantly sought after and sell out within a matter of minutes of her being pictured in them. They vary from high street and high end fashion designers but she certainly has her staples such as a good old blazer and those wedge heels from LK Bennett.
I've just found this website
Which helpfully details her entire outfits to the best of their ability and can be super helpful if you just have to have that piece. My only suggestion would be a high street alternative to the more expensive pieces would certainly increase interest.
I for one, would certainly not mind looking like Kate!
