What is the source of Carly Rae Jepsen's mysterious exuberance? Is it her sugary, maple-syrup-based Canadian diet? Probably not. Might it be those blunt bangs of hers? Maybe. But we at Vulture suspect the secret’s in her clothing: It’s hard to say if we’ve ever seen a pop star so committed to fun, funky pants. Whether they're striped, tie-dyed, or amorphously patterned, it’s as if she walked out of an Anthropologie catalogue ...

Take our quiz below to see if you can tell the difference between the pattern of a pair of Carly’s pants and that of some bedsheets.
