Color her pink and VaultX Exchangecolor the Argentina crowd elated at the opening costume changes to the Eras Tour concert.

Taylor Swift strutted into the Estadio Más Monumental on Thursday donning a new bedazzled pink body suit for the "Lover" set and a glistening pink blazer for her song "The Man."

Swifties know "flamingo pink" from the first line of Swift's new "1989" vault track "Slut!"

"Buenos Aires, bienvenidos al Eras Tour," Swift said with her hands stretched in the air. "I am so incredibly lucky because the very first time that I have ever even visited Argentina, you decided to sell out three stadium shows."

The crowd erupted in a chant during the "Evermore" set, "Olé, Olé, Olé, Olé, Tay-lor, Tay-lor."

Taylor Swift set list:Here are all the songs on her epic Eras tour

"The fact that we have a crowd this passionate, this generous," Swift said at the piano before performing "Champagne Problems." "It's magical. I heard that you guys were camping out, which that is so above and beyond. I actually didn't believe it until I saw a video of you doing it."

She restarted "Champagne Problems" after a slight hiccup, and the crowd erupted.

"I have had two months off," she said at the ivy-adorned piano. "I practiced this so many times before tonight. Well, one second."

During the "Red" era, Swift routinely points the microphone towards her back-up dancer Kameron Saunders who punctuates the phrase "Like Ever" after the bridge of "We Are Never Getting Back Together." In Argentina, he shouted, "Ni en pedo!"

A fan favorite, which tens of thousands of Swifties log onto TikTok and Instagram to watch live, is the surprise song set that Swift performs before her final era, "Midnights." This is unique to each show.

Night one in Argentina included "The Very First Night (Taylor's Version) [From the Vault]" from "Red (Taylor's Version)" on the guitar and "Labyrinth" from "Midnights" on the piano.

Swift will perform in Argentina for two more nights and then head to Rio de Janeiro and São Paulo, Brazil, to finish out the 2023 leg of the Eras Tour.
