CHICAGO — The much anticipated ‘Eras Tour’ is descending upon Chicago this weekend and Taylor Swift mania has officially taken over.

Swifties lined up outside Soldier Field Thursday morning to be among the first to get their hands on tour merchandise. The first fan got in line at 1 a.m.

Eras Tour merch sales began at 10 a.m. and are scheduled to close at 7 p.m. Thursday.

Skycam9 captured long lines of fans outside of tents where the merchandise will be sold from.

An advisory for fans without tickets discouraged concert hopefuls from gathering outside of the Soldier Field. “The stadium and surrounding areas will be at maximum capacity,” Soldier Field tweeted. “All parking lots are already sold out for each show night.”

“The Eras Tour” will be held at Soldier Field for three days — from June 2 through June 4 —and is completely sold out.
