There are some things in life on This Is Us [1] that just go hand in hand: Rebecca and her moon necklace [2], Super Bowl Sunday and Steelers jerseys [3], and of course, Jack and his mustache, which is why we were shocked to find out that his beloved facial hair almost wasn't a part of Milo Ventimiglia's character [4]. Earlier this month, Entertainment Tonight caught up with Zoe Hay, head of the show's makeup department, and Hala Bahmet, costume designer, on the set of the NBC show, and boy, did they have some great things to share. The part that most piqued our interest involved details about Jack's notorious mustache [5].

"I like Jack with the mustache, which was a hard sell in the beginning," Hay told the publication, explaining that the executive producers "didn't know if they were going to be 'happy'" with the facial hair, but when the razor was put away and Ventimiglia had a gloriously retro look, Hay said, "We were like, 'Too late! We already did it.'"

Ventimiglia previously explained to the site that he was the genius behind the mustache look [6]. "In the second episode of the first season, it was scripted that Jack was clean-shaven but eight years older, and I said, 'Maybe I should be wearing a mustache,'" he shared. "We shaved half of my face and we get a, 'Wait! Wait! Wait! Wait!'"

It was perfect timing for producers then, and now, we can't imagine the Pearson patriarch without his 'stache. Read on to see some of our favourite photos of Jack with a mustache, and catch up on everything to expect from season three of This Is Us here [7].
