Taylor Swift and Brittany Mahomes have seemingly become game-day besties. Together, the pair coordinated in custom Kansas City Chiefs puffer coats to brave the blistering cold and support their significant others at Saturday’s (Jan. 13) game against the Miami Dolphins.

The coats were made by designer Kristin Juszczyk, the wife of San Francisco 49ers fullback Kyle Juszczyk. Swift sported boyfriend Travis Kelce’s jersey number, 87, on hers, while Mahomes’ jacket displayed her husband Patrick’s number, 15.

“Twinning & Winning,” Mahomes captioned an Instagram photo collection from Saturday’s game, which ended in a 26-7 win for the Chiefs.

The Sunday Instagram post mostly consisted of several pictures of Mahomes with Swift, showing off their similar outfits. With a drink in hand, Swift was playful and silly in her poses next to Mahomes.

Juszczyk, who designed the ladies’ Chiefs outerwear, shared her reaction to them wearing her designs on Saturday with a behind-the-scenes video of herself making the coats. “An honor of a lifetime!!!!!” she wrote. “Thank you @taylorswift & @brittanylynne.”

Swift — who sat next to Kelce’s mom, Donna, at the game — wore her ’87’ coat with an all-black ensemble and Louboutin combat boots.
