First up? Styles for the classic groom. Leo DiCaprio and Hugh Jackman look similar enough at first glance, but further exam shows that Leo chose a notched lapel with rounded edge bow tie, while Hugh chose a peaked lapel and pointy edged tie.
Bryan Cranston chose a pointed end bow tie, and Chris Tucker went big and floppy.
I know, there's only such much you can do to dress up a black tux. Don't worry, Al Roker and Aaron Paul were reppin' for the non-conformist guys. Both chose blue plaid tuxes, Al's was in your face with the addition of green and Aaron's was subtle.
