It may be cold (like, really cold). But that’s no excuse to run around town in the equivalent of a spacesuit. Don’t believe us? Check out Katy Perry in London. Her striped mini-dress and thigh-high boots are killin' it, but what really seals the deal is the fun faux-fur coat. Not sure you can pull off a full-on furry yellow jacket? Dabble with a collar, a hat or even a funky purse. Trust us, you'll look fur-bulous (oof, sorry—couldn't resist)!
