The Kelce family supported Travis Kelce and the Chiefs in authentic style at the Super Bowl LVIII in Las Vegas on Sunday

The Kelce family is nothing if not supportive!

Travis Kelce’s mom, Donna Kelce, brother, Jason Kelce, and sister-in-law, Kylie Kelce, all rocked something to support the Kansas City Chiefs tight end for the 2024 Super Bowl in Las Vegas.

Jason, 36, who plays for the Philadelphia Eagles, went full throttle for his look, wearing Chiefs overalls, while his wife, Kylie, 31, was more subtle. She wore a Chiefs-red long-sleeve tee with the University of Cincinnati logo (the Kelce brothers’ alma mater) with an “Alright Nah” tee underneath (a nice nod to Travis).

Mama Kelce, on the other hand, wore a custom coat for the game. Her black coat had “Super Bowl LVIII” on the back, along with “Mama Kelce” on the bottom. The sleeve had Travis’ jersey number written on it.

Ahead of the NFL championship, in which Travis, 34, and the Kansas City Chiefs are taking on the San Francisco 49ers, Kylie opened up to PEOPLE about her very casual and comfortable game-day style.

“I would love to tell you that I have a game day fit planned out, but I am a very last-minute person,” she tells PEOPLE.

Even her looks for Philadelphia Eagles games — where she would support husband Jason, the team’s star center — are “not thought out in advance,” she tells PEOPLE.

“Last year for the Super Bowl, I wore what I had been wearing for really all of the playoffs, because I didn’t want to mess with the Juju,” she adds. “So I am not trying to do anything fancy, or anything out of the ordinary for myself.”

And, giving a slight hint about her Super Bowl LVIII ensemble, Kylie said she will certainly stay true to her style roots, even if she puts a formal spin on it for the occasion.

“I would guess that I will be — even if I elevate my look a little bit — it will still be comfy for sure,” she added.
