You know what it's like when you think you're going out for a quiet, low-key dinner, but in fact your S.O. is secretly planning an epic party celebrating every version of you ever,” as I do, and Taylor Swift does. [Swift's boyfriend, Travis Kells, seemed to pull off exactly this feat when he surprised her with an Eras Tour wrap party in Kansas City on Wednesday night.

According to Swift's friend, stylist and designer Ashley Avignone, the night started with a lie. In the caption of an Instagram post filled with photos of the glamorous party, Avignone revealed that the “Fortnite” singer had no idea about the Elas Tour party, and that Kelsey had apparently convinced her that they were just going out for a chill dinner She revealed that she had.

“She thought she was going to a small, quiet dinner, but it was actually a huge surprise party involving her friends, family, and props🥳,” Avignone wrote.

The party was completely period-themed, with guests dressed in costumes inspired by various eras and specific moments (Travis-Kelce dressed as Partick-Mahomes on stage at Eras-Tour-in-London).

Swift's Eras-Tour wrap party look was a bathtub-full-of-diamonds level of extravagance. According to the jeweler's website, a $4,290 Balmain mini dress (styled by Joseph Cassell Falconer) was adorned with DeBeers diamond drop earrings worth $36,000.

The Eras tour wrap party was clearly a success, but Swift is reportedly ready to embrace the “simple life” for a while in the post-Eras era.

“Taylor had such a great time and is sad the tour is over, but is eager to spend some time away from the spotlight,” a source close to the couple told The Sun. 'She wants to keep things simple for a while.'
