The Grammy winner supported boyfriend Travis Kelce at the Kansas City Chiefs’ game against the Las Vegas Raiders on Monday, dressed in a festive red crewneck sweater and plaid Hill House Home skirt ($150).

She kept warm in her cashmere bomber jacket from pal Gigi Hadid’s Guest in Residence line, along with a pair of diamond-patterned Sheertex tights that are currently on sale for 30% off.

She topped off her holiday getup with a Santa hat featuring Kelce’s jersey number, 87, and wore her go-to red lipstick.

Since she began dating the tight end this summer, Swift’s become a fixture at his football games, often clad in vintage team merch and accessories that honor her beau.

She’s the proud owner of friendship bracelets adorned with Kelce’s nickname and jersey number from Erimish, a Missouri brand beloved by Chiefs players and their families.

And earlier this month, she showed up in the suite wearing a Kut the Knit beanie stitched with an “87,” another nod to her man.

She’s also been spotted in a Chiefs windbreaker from Wear by Erin Andrews, a line founded by the sports reporter who helped get Swift and Kelce together in the first place; the zip-up sold out in no time.

“Her fans, they’re so powerful. They just want to get close to whatever she’s associated with. I find it fascinating,” Andrews told Variety. “She put a spotlight on the sport. Let’s embrace it.”

But no sartorial shoutout got Swifties talking quite like the gargantuan opal-and-blue-topaz ring the “Cruel Summer” singer debuted on her 34th birthday, which features both Swift’s and Kelce’s birthstones.

While fans originally assumed the sparkler was a surprise from the athlete, Miles Teller’s wife, Keleigh Sperry, later revealed she was behind the gift.
