Taylor Swift wore a custom winter coat by fashion designer Kristin Juszczyk to the Chiefs-Dolphins playoff game at GEHA Field at Arrowhead Stadium Saturday. The designer is married to San Francisco 49ers fullback Kyle Juszczyk

Taylor Swift bundled up for historically cold football weather in Kansas City Saturday in an outsized, custom winter coat big enough to hold two tight ends. The coat was made by Kristin Juszczyk, a fashion designer married to San Francisco 49ers fullback Kyle Juszczyk, and she’s making a splash in NFL style circles.

She has made clothing for several athletes and NFL wives, including Simone Biles (married to the Packers’ Jonathan Owens) and Brittany Mahomes, wife of Chiefs quarterback Patrick Mahomes and co-owner of the Kansas City Current soccer team. In fact, Brittany Mahomes also wore a custom coat by Juszczyk sporting her husband’s No. 15 on it.

Juszczyk posted a video to her Instagram showing the making of Swift’s coat. “An honor of a lifetime!!!!! Thank you @taylorswift & @brittanylynne,” she wrote.

The coat represents Juszczyk’s goal to “reinvent the jersey.” She turned one of her husband’s jerseys into a jacket similar to the one Swift wore Saturday. She told Yahoo Sports that her most popular piece so far was a Brock Purdy vest she made for 49ers wide receiver Deebo Samuel. Purdy is San Francisco’s quarterback. Swift has set a high bar when it comes to football fan fashion. Her custom coat wasn’t the only eye-catching part of her outfit. Her fans lusted after the red-soled Christian Louboutin Panaroot Dune combat boots she wore. Black. Round-toed. Made in Italy.
