The recently opened Rumpuree Dance Studio in Bangkok's Amarin Plaza offers erotic dancing and stripteast classes to otherwise conservative Thai women who feel the need to let loose and relieve stress. Most of the attendees of the classes are educated, upper-middle-class career women between the ages of 20 to 50, according to Busakorn Vorameth, the studio's owner. The first half hour of the class involves stretching while the lights are dimmed and soft music is played.  But during the second hour, the lights are turned on, the music's tempo increases, and the instructor teaches the pupils sexy moves while dancing in front of a mirror.  Busakorn said that along with exercise and stress reduction, the class can help women to become more comfortable with their bodies.
