When it comes to fashion, few things frustrate me more than when a celebrity seemingly spends hours putting together a red-carpet look, and then ruins it by throwing on an uncomplimentary (or just plain bad) cover-up. Recent offenders include Kelly Osbourne, Kate Bosworth and January Jones, all of whom successfully spoiled their evening gowns with jackets that proved ill-fitting, too casual or (in Kate's case) both (add to that too hairy and from a different season).
Perhaps they should take a cue from Olivia Palermo, who's mastered not only the art of coat pairing, but also layering.
Which rookie's coat pairing proved worst?
