The Princess of Wales is nothing if not consistent with her fashion choices. Yes, she's adapted certain items to fit in with current trends, like trading slim, cropped pants for wide-leg, extra-long trousers. Overall, however, she's been amazingly unyielding in her love of coat dresses, pointy-toe pumps, skinny jeans, A-line dresses, knee-high Penelope Chilvers boots, and even her tiara of choice, the Lover's Knot, which she's been regularly re-wearing for over a decade despite having access to dozens of other styles.

Another signature element of Kate Middleton's wardrobe is the absence of logos. She has never been into the logomania trend, preferring a quiet-luxury approach instead. Yesterday, however, she made a rare exception. The princess greeted the Sultan of Oman at Windsor Castle wearing a Chanel Small Classic Flap Handbag ($11,700) with an Alexander McQueen coat, Manolo Blahnik shoes, Cassandra Goad earrings, and a Juliette Milinery hat. Naturally, if she's going to wear a logo, it's going to be a timeless one—and there's nothing more enduring than a quilted Chanel bag. Scroll down to see her outfit and shop her exact bag.
