American singer Beyoncé has embarked on six concert tours during her solo career, four of which have been worldwide and two of which have been collaborative.  Her solo tour debut (whilst on hiatus with Destiny's Child) began in 2003, with the Dangerously in Love Tour.  Based predominantly in the United Kingdom, the tour received an unfavorable review from Dave Simpson of "The Guardian" based on Beyoncé's costumes and a confusion of her core audience at the time.  In 2007, she embarked on her first major solo world tour – The Beyoncé Experience, following Destiny's Child's disbandment in 2005.  The tour visited five continents and Beyoncé was lauded by music journalism for her simultaneous dancing and singing abilities.  Following the release of her 2008 third studio album "I Am... Sasha Fierce", Beyoncé embarked on her next world concert venture, the I Am... World Tour.  She collaborated with Thierry Mugler exclusively for the tour's costumes.  The I Am... World Tour also marked the first time Beyoncé had performed in South American countries.  Beyoncé saw her most commercially successful tour to date with 2013-2014's The Mrs. Carter Show World Tour.  Grossing US $229,727,960, the 132 date venture was criticised for the name of the tour, as Beyoncé appeared to be letting herself be known as simply Shawn "Jay-Z" Carter's wife, despite being proclaimed as a "modern-day feminist".  The tour itself however was lauded by music critics, who again praised Beyoncé's performance abilities and the more advanced production seen compared to her previous tours.
