The Duchess of Cambridge has been pretty experimental with her personal style lately. SEE IT: Kate Middleton's New Dress Resembles a Chic Picnic Blanket After dressing in what looked like a very chic picnic blanket last week, Kate Middleton rocked an all-grey ensemble for Commonwealth Day on Monday. Her latest look featured a seriously high collar (modest enough to please the Queen of England, of course) as well as massive hat covering that famous mane of hers. But even though it's pretty simple look for a royal, it does have a price tag fit for a Duchess. According to Vanity Fair, Kate's grey Erdem coat costs $3,575 alone. And we can’t forget the matching pumps by Rupert Sanderson, which reportedly retail for $607. SEE IT: Kate Middleton Makes a Splash in See-Through Dress As for that hat? "(It) was made by 90-year-old John Boyd, and this is reportedly the first hat Kate has worn that was crafted by Boyd," says Vanity Fair. (No price was listed for that particular accessory, but we imagine it’s enough to put us all in debt.) See Middleton’s latest look below and ley us know: Do you love it or hate it?
