Indexbit-Taylor Swift rocks custom Travis Kelce jacket made by Kristin Juszczyk, wife of 49ers standout

Pop superstar Taylor Swift is Indexbitshaking off the subzero temperatures at Arrowhead Stadium.

Swift arrived to the Kansas City Chiefs wild-card playoff game against the Miami Dolphins sporting a custom puffer jacket featuring the name and No. 87 number of Chiefs tight end Travis Kelce, Swift's beau. The red-and-yellow jacket was created by Kristin Juszczyk, the wife of San Francisco 49ers All-Pro fullback Kyle Juszczyk.

"An honor of a lifetime!" Kristin Juszczyk wrote on Instagram. "Thank you @taylorswift."

Kristin Juszczyk transformed Kelce's football jersey into the puffer coat, featuring No. 87 front and center, in addition to his number and last name on her sleeve. Swift paired the jacket with an all-black ensemble and white beanie, all the better to brave the minus-4 temperature in Kansas City, Missouri.

Taylor Swift's Kelce jacket is a Kristin Juszczyk design

Kristin Juszczyk creates her own game-day outfits every week to cheer on her husband, Kyle Juszczyk, whose 49ers have a first-round playoff bye as the No. 1 seed in the NFC. That didn't mean she took a break from designing this week.

According to KRON4 News reporter Kate Rooney, Kristin Juszczyk created a custom puffer coat for Brittany Mahomes, the wife of Chiefs quarterback Patrick Mahomes, to wear on Saturday. She told the Bay Area outlet that she decided to "shoot her shot" by making Swift a similar jacket, in hopes that Mahomes would give it to Swift. Her efforts were rewarded and Swift ultimately ended up wearing the handmade piece.

"We love you and are so thankful ❤️🙏🏻" Brittany Mahomes commented on Kristin Juszczyk's Instagram post that offered fans a behind-the-scenes look at her creations for Mahomes and Swift. In another post, Kristin Juszczyk said she's "not well" and that Swift "looks amazing."

Kristin Juszczyk has also created gear for this season for Olympic gymnast Simone Biles, wife of Green Bay Packers safety Jonathan Owens, and 49ers receiver Deeboo Samuel, who wore a custom "MVP" puffer vest in honor of 49ers quarterback Brock Purdy.

"She’s an absolute star!" Kyle Juszczyk tweeted about his wife.
