Apparently a genuine bear fur hat, the historical original kind you can’t get any more, kids deadpool costume was unceremoniously ‘trimmed’ by a costumer during the filming of a commercial. You don’t want to get the wrong size because not only will the costume not fit properly; you won’t be able to return the costume back for a refund if you picked the wrong size. Save the measurements down on paper or on your computer for future reference; these numbers will be handy because every site has their own different sizes.
