Burnt orange and royal blue -- I'm in Pantone color heaven. This fashionista's colorful pairing is perfect for fall, and I fully intend to emulate this outfit with my own wardrobe. Whether your go-to fall outfit is sweater dresses and boots, or oversized sweaters and skinny jeans, break out your color wheel and take notes.

This perfectly polished ensemble could very well hang in the closets (I'm guessing she has more than one) of everyone's favorite royal. You can never go wrong with classically tailored boxy jackets and pencil skirts, but fun patterns and textures are a fresh take on the style. Polka dots, stripes, or florals are all acceptable to mix and match in today's rule-breaking fashion climate.

Oh, Karl Lagerfeld. We love you for your completely quotable diatribes, your cat's Twitter account, and of course your iconic style. Model Liu Wen plays homage to the fashion great with this quirky caricature T-shirt, giving us our next Casual Friday ensemble. A quirky graphic tee, dark wash skinny jeans, printed cardigan and menswear shoes. Bonus points if you can find a pair of these amazing metallic oxfords.
