Taylor Swift and her pals know style … dressing up in honor of the pop star at an “Eras” tour-themed party — with Brittany and Patrick Mahomes paying homage to a viral moment.

Mrs. Mahomes posted several photos from the party to her Instagram just about an hour ago … showing off her silver outfit covered in fringe — clearly an interpretation of T-Swift’s own outfits on tour.

Brittany had Patrick dressed up too … black tux with a white undershirt and bow tie — complete with a black top hat hanging off his thick curls.

The two aren’t just dressed dapper here — they’re actually paying respect to a viral moment between Patrick’s bestie Travis Kelce and Taylor … when he joined her onstage at Wembley Stadium in London over the summer.

Posting with Taylor and Brittany at the event … Ashley Avignone, a friend of Taylor’s and Lyndsay Bell, another Chiefs WAG.

Brittany captioned the pics “My people” … so sounds like they’re a tight-knit group.

Of course, Taylor and Britt became fast friends after the pop star started dating the Chiefs tight end last season … hanging out at football games, grabbing dinner and even vacationing at the beach together.

Rumors of tension between the two began to circulate earlier this year … but, clearly it was all speculation — nothing real behind it.

While it’s not clear exactly when this party happened, Taylor’s birthday was Friday … so, there’s a very good chance this was Taylor’s friends way of celebrating her.
