Black jeans may be a wardrobe staple year round, but, come the holiday season, they become a flat-out necessity. (For us, anyway.) You can wear ‘em casually to the office with a pair of flats, and then throw on a pair of heels and be ready for that party after work. And there are so many types of black jeans to choose from these days: Basic black, coated, with suede or leather side panels, and so on. But the best part of all might be that not only are black jeans more comfortable than your standard dress-and-tights holiday combo, but they might just actually be a bit more chic. Sleek. Sophisticated. See: Miranda Kerr and Gwyneth Paltrow for proof.
