She’s throwing it back.

Brittany Mahomes went for a black-and-white look to support husband Patrick Mahomes at the Kansas City Chiefs vs. Cincinnati Bengals game on Sunday, suiting up in an all-Chanel ensemble.

The personal trainer, 29, chose a vintage black minidress from 1997 featuring the fashion brand’s name all over it — with the style selling on the resale market for a whopping $5,499.

She went for a totally logomania outfit, adding a pearl necklace with Chanel’s iconic “CC” logo and a pair of loafers ($1,360) with the brand’s name again spelled out across the tongue.

Brittany, who is currently pregnant with her third child, topped the look off with a black blazer and her go-to oversized sunglasses and piled her hair up into a top knot.

She shared photos on Instagram with daughter Sterling, 3, and son Bronze, 1, on the sidelines, with the former sporting a custom “Mahomes” dress and the latter his dad’s Chiefs jersey.

The quarterback, 28, also went for a logomania look when he arrived at Arrowhead Stadium in Kansas City, Mo., rocking a monogram-covered Louis Vuitton white T-shirt and holding a white backpack from the brand ($2,820).

While Brittany appeared to sit separately from good friend Taylor Swift, the two were somewhat coordinated, with the pop star, 34, also choosing a vintage look.

Swift, who is dating tight end Travis Kelce, showed up to the game wearing an oversized 1995 Chiefs T-shirt dress from a local Kansas City shop.

Swift and Brittany have matched on a few occasions, including at the Jan. 14 game against the Miami Dolphins.brittanylynne/Instagram
There doesn’t appear to be tension between the pair despite Brittany recently “liking” Instagram comments that supported Donald Trump for president while the “Bejeweled” singer officially endorsed Kamala Harris after last week’s debate.

Trump, 78, has since bashed Swift and praised Brittany, while Patrick stayed neutral when asked about the upcoming election.

While the two blonds have yet to take in a football game together this season — sitting separately at last week’s Chiefs season opener against the Baltimore Ravens — they hit New York City with their men in tow, showing out at the US Open and grabbing dinner afterward.
