The «Who's That Girl World Tour» is the second concert tour by Madonna.
The tour supported her third studio album, «True Blue» (1986), as well as the soundtrack «Who’s That Girl» (1987).
It was Madonna's first world tour, reaching Asia, North America and Europe.
Musically and technically superior to her previous «The Virgin Tour», «The Who's That Girl Tour» incorporated multimedia components to make the show more appealing.
Madonna trained herself physically with aerobics, jogging and weight-lifting, to cope with the choreography and the dance routines.
For the costumes, she collaborated with designer Marlene Stewart, expanding on the idea of bringing her popular video characters to life onstage, reworking scenes from videos such as «True Blue», «Open Your Heart», «Papa Don’t Preach» and «La Isla Bonita».
The stage was huge, with four video screens, multimedia projectors and a flight of stairs in the middle. Patrick Leonard, who was the music director, encouraged Madonna to go with the idea of rearranging her older songs and presenting them in a new format. The title «Who's That Girl» came to Madonna's mind when during rehearsals one-day when she looked at a gigantic image of herself, projected on a screen on the stage.
The show consisted of seven costume changes, with song-and-dance routines, theatrics, addressing social causes—during «Papa Don't Preach»—as well as an encore, consisting of the «Who's That Girl» film title song and «Holiday».
The tour was critically appreciated, who commented on the extravagant nature of the concert and complimented Madonna for her dancing, costume changes and dynamic pacing.
After the tour was announced, the first two shows at Wembley Stadium in London sold-out at a then record-breaking time of 18 hours and 9 minutes for 144.000 tickets.
Madonna's concert in Paris in front of 130,000 fans remains to this date, her biggest concert audience ever.
A concert was also planned in Basel, Switzerland for August 31, 1987, but negotiations between Madonna's management and local organizers failed due to the high fee (U.S. $1 million) that Madonna's camp demanded.
As a result Nice, France was booked in the itinerary.
Her first-ever Italian concert in Turin, was presented by the Italian state broadcaster RaiUno and broadcast around the world. Just in Italy, the show was watched by around 14 million households. The show at Turin was watched by 65.000 fans and was a record there.
In Japan, a thousand troops had to restrain a crowd of 25.000 fans seeking to greet Madonna at the airport. When severe storms forced the cancellation of her first shows, despondent fans nearly rioted, and Madonna was confronted with out-of-control teenagers soaking themselves in the rain outside the stadium. Promoters had no choice but to refund U.S. $7 million to ticket-buyers.
Madonna's Madison Square Garden show in New York City was an AIDS benefit with all the proceeds from the show going to «American Foundation for AIDS Research» (AmFAR). She dedicated her performance of «Live To Tell» to her late friend Martin Burgoyne, the designer of her 1983 «Burning Up» single cover sleeve.
Upon completion, the tour was the second top female concert tour of 1987, behind Tina Turner's «Break Every Rule Tour», earning in total of U.S. $25 million according to Pollstar and playing in front of 1.5 million audience all over the world.
