Over the past three seasons, audiences have fallen in love with Jack and Rebecca's love story [1] on This Is Us [2], so it comes as no surprise that they inspired quite a few Halloween costumes [3]. You can either don Jack's iconic mustache and Rebecca's Steelers jersey, or get a little more creative by carrying around their own "Big Three." For more inspiration, see some of the best fan costumes ahead. We have a feeling Jack Pearson would be very proud of these.
