[Givenchy Creative Director] Clare Waight Keller did a spectacular job creating this piece of art for us."

The actor's stylist knew the only person who could pull off a red velvet tux was Armie.
Stylist Ilaria Urbinati told PEOPLE that she worked with the Armani design team on this red velvet custom suit because "I knew if anyone could pull it off, he could." She also kept the look streamlined by leaving out a contrasting lapel or pant stripe. "I didn't want any black on it, not even the button. Because to me that goes 'Hugh Hefner' or 'Dracula' fast. I wanted the look as clean as possible since it’s a lot going on with the color and the fabric."
