In 1939, Artist Cat Tuong had a breakthrough step to make a new style of Ao Dai – Le Mur Ao Dai (French name of artist Cat Tuong). Le Mur Ao Dai hugged the curve of the body with more western details such as bulging arms, and a heart-shaped collar that was attached with a bow. There were many variations to this style – Le Mur Ao Dai had to be worn with white pants, high heels, an umbrella and a purse. However, at the time, this ‘Ao Dai’ was considered too sophisticated and indecent. People didn’t accept this change and refused to wear it widely. Till 1943, Le Mur was forgotten.
