As Taylor Swift’s relationship with Travis Kelce heats up, so does her game day style. The singer is proud to show her support for Kelce in the stands, and continues to serve up outfit inspiration for her fans.

For Sunday’s game between the Kansas City Chiefs and Buffalo Bills, Swift, 33, returned to Arrowhead Stadium in Kansas City, Missouri, cheering for her tight end boyfriend, 34, in another great outfit (that already sold out swiftly).

The powerhouse performer wore a vintage red-and-black Chiefs sweatshirt from the ’90s from local Kansas City retailer Westside Storey— and the $250 style is no longer available on the store’s website. She teamed the retro topper with her signature red lip.

Swift’s latest game day appearance follows her Time 2023 Person of the Year interview, where she broke her silence about her relationship with Kelce for the first time — even giving a breakdown of the timeline, confirming that her relationship with the NFL star, 34, “all started when Travis very adorably put me on blast on his podcast, which I thought was metal as hell.”

“We started hanging out right after that. So we actually had a significant amount of time that no one knew, which I’m grateful for, because we got to get to know each other,” Swift, 33, continued.

She confirmed that the first time she supported Kelce at a Chiefs game in September, they “were a couple,” adding, “I think some people think that they saw our first date at that game? We would never be psychotic enough to hard launch a first date.”

As for the NFL’s fixation on her presence at games and the cameras often flashing her cheering on screen, the 12-time Grammy winner pointed out that she’s “just there to support Travis” and the rest is just noise out of her control.

“I don’t know how they know what suite I’m in. There’s a camera, like, a half-mile away, and you don’t know where it is, and you have no idea when the-camera is putting you in the broadcast, so I don’t know if I’m being shown 17 times or once,” she said. “I have no awareness of if I’m being shown too much and pissing off a few dads, Brads and Chads.”

She does, however, make sure to dress the part of a WAG and brings her sophisticated interpretations to game day style, elegantly pairing Chiefs colors — like her red Stella McCartney teddy bear coat at the Green Bay Packers game last week — with chic knee-high boots and pleated skirts.

She also often pulls Chiefs merch to show her support, and almost everything she touches turns to sold.

When the Chiefs faced the Denver Broncos in October, Swift paired her black leather mini skirt with an oversized red, white and black Chiefs windbreaker jacket — from Wear by Erin Andrews — which she wore off her shoulders.

Andrews opened up to PEOPLE about the “Taylor Swift Effect” and the newfound visibility it gave her brand.

“It’s had an amazing effect,” Andrews told PEOPLE of Swift’s support. “Not just on our Kansas City Chiefs stuff, but I’m getting DMs and mentions in pictures of women in our Ohio State gear, our Miami Dolphins gear, our baseball gear as we’re in the World Series. They’re like, ‘Well if Taylor Swift is going to wear it, I’m going to wear it!’ So it’s just been pretty fascinating and so cool to watch.”

She added, “Obvious anything she touches [is gold].”
