Under the bright sun...: Under the bright sunshine, Hanoi schoolgirls in traditional `Ao Dai` dresses and conical hats cycle through Phan Chu Trinh Street. Ao Dai in their modern form first appeared in 1930, designed by Cat Tuong or, as the French knew him, Monsieur Le Mur. Today, the popularity of the dresses has spread beyond Vietnam's border. /KTS
