The show reportedly cost an estimated £3 million to stage, with £250,000 worth of pyrotechnics. Girls Aloud called the show their most "extravagant and rewarding" yet. Sarah Harding said that "over the years it gets bigger and more elaborate." The stage outfits were designed by Welsh designer Julien MacDonald, London-based Norwegian designer Kristian Aadnevik, and Liza Bruce. MacDonald designed "a set of crystal beaded numbers drenched in his signature sparkle" and "a collection of sci-fi inspired bodysuits." Kimberley Walsh told press that the band was "really excited about the tour" and had "loads of things planned." Luigi Masi, Billiam and The Saturdays provided support for Girls Aloud on the tour. Girls Aloud played a number of festivals and open-air concerts over the summer. They were scheduled to perform at the Beamish Summer Festival, held at Beamish Hall in August as part of a two-day event organised by Hope 4 Kidz. However, due to weather problems, the concert was cancelled. Girls Aloud also played at Pop in the Park and 2008's V Festival. They previously performed at V Festival in 2006 with a shortened set of their Chemistry Tour. For the opening of the Tangled Up Tour, the band members were suspended from the ceiling wearing black cloaks. The video screen shows Cheryl Cole singing the vocodered intro to "Sexy! No No No…". Girls Aloud reached the stage as the song became more uptempo, removing their cloaks and revealing sci-fi inspired bodysuits. They then perform "Tangled Up" album track "Girl Overboard". During "Sound of the Underground", Girls Aloud use "semi-naked male dancers as both props and furniture. The first section of the show is finished by "Close to Love", another album track. For the second section of the show, Girls Aloud wear black cabaret numbers. They perform "Can't Speak French", followed by "Love Machine". Album track "Black Jacks" is "performed on a rotating stage complete with a hugely energetic dance routine from both the girls and their dancers" and features a "snappy monochrome stage design." "Biology" is "slowed down slightly" and "interrupted" with a jazz interlude. During their ballad section, Girls Aloud perform "Whole Lotta History" and "I'll Stand by You". They also perform a stripped-down cover of Robyn's "With Every Heartbeat".
