work with anything." As for the hair, it was changed at every show to fit the vibe of the city. For example, at the Uniondale show on August 2, 2011, Spears sported wavy hair, inspired by Sarah Jessica Parker and the street style of New York women. BuzzFeed reported that 23 18-wheeler trucks arrived at each venue at 5 a.m. on show day. It took 7 hours to unload and build the stage. Unlike most tours who built the stage from the bottom up, the stage was built from the ceiling down. The tour comprised 140 workers, 125 crew members, 14 tour buses, 16 dancers and 2 band members.
