He’s in his tuxedo era.

Travis Kelce, 35, celebrated girlfriend Taylor Swift with a surprise Eras Tour wrap party, where he dressed on theme in a familiar costume.

After arriving in a very “The Tortured Poets Department”-style brown Vivienne Westwood cardigan ($625 $494) and glasses, the Kansas City Chiefs tight end revived the sharp tuxedo and matching top hat he wore to make a surprise appearance on stage during her London show in June.

Kelce appeared as part of a skirt during “I Can Do It With a Broken Heart” at the tail end of the three-hour concert, picking up Swift, 35, in his arms and attempting to “revive” her.

He then carried his beau to a red couch, continuously yelling, “Wake up!” and fanned her once he plopped her down.

Though the fan from the performance didn’t make a cameo at the party, Travis had all the other outfit details down pat, even wearing his top hat at times — including to make a speech at the celebration.

Kelce wasn’t the only guest who paid homage to the singer via their ensembles, with teammate Patrick and wife Brittany Mahomes absolutely nailing it with their looks.

The pregnant Kansas City Current co-owner rocked a mashup of “Fearless” and “Midnights”-inspired elements, which included a black and gray fringe Alice + Olivia jacket, coordinating minidress and sparkly boots.

Meanwhile, her football star husband matched Kelce in the same black tuxedo and complementing top hat.

The lady of the evening looked sensational in a black Balmain minidress ($4,290) and dangly diamond earrings ($36,000) from De Beers.

Swift rounded out the party ensemble with Christian Louboutin’s black velvet pumps — a fitting choice as the luxury shoe designer crafted all her heels for her Eras Tour costumes.

In some snaps, the Grammy-winning musician is pictured on the dance floor with a pair of square-shaped sunglasses.

The end of the Eras tour isn’t all that the Grammy winner has had to celebrate this month; Swift turned 35 on December 13, choosing a low-key intimate night in with her boyfriend rather than a major bash.

Kelce reportedly made sure his girlfriend’s day was “meaningful,” a source exclusively told Page Six.

“Travis had jewelry engraved especially for Taylor, he gave her countless roses and showered her in gifts,” the source revealed.

“He hired a private chef and bartender to cook and make cocktails for them. He had his gifts delivered beforehand so they would be a surprise.”
