Why you'll be seeing a lot of Harry Styles fans in the East Village over the next few months

With Harry Styles starting his 30-night run at Madison Square Garden tomorrow night, expect to see plenty of his fans making a pre-show pilgrimage to the East Village in the months ahead. 

A "Together, Together" pop-up opens tomorrow at 22 E. Second St. between Second Avenue and the Bowery, featuring merchandise tied to Styles' current world tour. 

The pop-up will be around nearly as long as Styles in NYC on this tour: through Nov. 1, open Wednesdays through Sundays. Hours are noon to 7 p.m., with American Express cardholders getting early access from 11 a.m. to noon. 

Styles is playing the Garden every Wednesday, Friday and Saturday from Aug. 26 through Oct. 31. 

And the Second Street storefront is getting accustomed to hosting a fan base: Earlier this month, the space was home to the Rush pop-up during the band's 50th-anniversary run at the Garden.
