The discussion in this thread has been quite complete on the issues of nudity in public except for one point. There is no research that shows that children are harmed by exposure to nudity. In fact, exactly the opposite is true. According to a definitive 18 year long study, children exposed to nudity had delayed onset of adolescent sex and less adolescent sex. Boys were less likely to steal or use drugs. The study was done by the UCLA Family Lifestyles Project in the Department of Psychology at UCLA (complete citation: "Early Childhood Exposure ..." by Paul Okami Ph.D., et al. in Archives of Sexual Behavior Vol. 27, No. 4, 1998, pp. 361-384).
