49ers' McCaffrey, Olivia Culpo Tease Kristin Juszczyk Design After Taylor Swift Video

Forget the six teams that advanced during the NFL's Super Wild-Card Weekend, the biggest winner was Kristin Juszczyk.

Kristin, the wife of San Francisco 49ers fullback Kyle Juszczyk, has been designing custom NFL merchandise for celebrities and the significant others of players to wear to games. The business took off on Saturday night when Taylor Swift wore a Travis Kelce coat to Arrowhead Stadium for the game between the Miami Dolphins and Kansas City Chiefs.

As the 49ers prepare to make their playoff debut on Saturday night, Kristin is preparing a special item for Olivia Culpo, the fiancée of San Francisco running back Christian McCaffrey.

In a recent post on her Instagram Stories (h/t Jaclyn Hendricks of the New York Post), Culpo was in a gym with Kristin Juszczyk.

"@kristinjuszczyk design loading…..," Culpo wrote on the caption, "She brought it in for me to try on. Anything to procrastinate actually working out."

Juszczyk's Instagram Story included a brief screenshot of McCaffrey's name being stitched onto an item.

No one was happier about Kristin's mainstream breakout moment than her husband. Kyle was making sure everyone who wondered where Swift got her jacket from knew it came from Kristin.

"Just pure joy," Kyle told reporters on Tuesday about Kristin's big breakout. "Just for her to get that recognition. She's been working so hard for so many years."

Culpo's custom item from Kristin Juszczyk will be unveiled on Saturday night when the 49ers host the Green Bay Packers at Levi's Stadium in the NFC Divisional Round.
