Taylor Swift has a message for her most devoted and detail-oriented fans.

At her second Eras tour performance in Miami, Florida on Saturday, October 19, Swift expressed special thanks to the audience for noticing and reacting to her latest onstage outfit change.

“You guys are the most rewarding group to show off your new outfits. Because this is a brand new dress that I have never worn before. And I feel like you guys noticed,” Swift told fans, according to People, after she walked out in a new Roberto Cavalli blue and purple gown featuring a plunging neckline for the show's acoustic set.

“It's really fun,” she continued, after showing off her new outfit to the delight of her fans. It makes me happy."

The new shiny blue gown was one of several new outfits Swift unveiled on the final leg of her history-making Eras tour, which kicked off on Friday, October 18 with a Reputation-era performance in Roberto Cavalli's black and gold brand new catsuit was unveiled, shocking fans.

As Marie Claire previously reported, the one-legged jumpsuit features a mesh and black sequin base with a 3D cobra wrapping up Swift's legs, covering her torso, and extending to her neckline.

Its scales (visible from the reporter's seat hundreds of feet away) are composed of gold baguettes, black bezels, and crystal stone accents. In addition, a golden serpent is entwined around Swift's covered arms and gizzard.

“These variations usually provide us with the expanse of the established world she created within her time,” Sarah Chapelle, author of the New York Times bestseller Taylor Swift Style, in a previous interview told Marie Claire.

“Most of the costume variations generally vary slightly in color and silhouette, but the goal is always to build on the customary ‘dress code’ of each era.”

The new Reputation-era outfits only add fuel to the already raucous speculation that Swift is preparing to release Reputation (Taylor's Version).

One hint, according to rabid Swift fans, came when Swift left the stage at London's Wembley Stadium on August 17 for her Eras tour.

During the performance, Swift left the stage with “very obvious snake-like movements,” Marie Claire previously reported.

On August 18, fans noticed Wembley flashing red and green.
