The Culture of Vietnam is one of the oldest of such in the Southeast Asia region. Although Vietnam lies geographically in Southeast Asia, long periods of Chinese domination and influence has resulted in the emergence of many East Asian characteristics in Vietnamese culture, and generally Vietnam is said to be part of the East Asian cultural sphere, known widely as Chinese cultural sphere.

Despite considerable foreign influence, Vietnamese people have managed to retain many distinct native customs which have always played a vital role in daily Vietnamese life throughout the millennia. While Chinese culture has the largest foreign influence on traditional Vietnamese culture, there is also a much smaller influence from the Cham and later Western cultures (most notably that of France, Russia and the United States).

In terms of prehistory, most Vietnamese historians consider the ancient Dong Son culture to be one of the defining aspects of early Vietnamese civilization.

The beauty of women dressed in ao dai always leaves a deep impression on foreign visitors to Vietnam. Girl students dressed in white long robes take to streets on the way to schools or back home, or gracefully sail on their bikes along streets. Female secretaries in delicate pastels greet you at an office door and older ladies in deep shades of purple, green or blue cut a striking pose at a restaurant dinner. The ao dai appears to flatter every figure.

Its body-hugging top flows over wide trousers that brush the floor. Splits in the gown extend well above waist height and make it comfortable and easy to move in. Although virtually the whole body is swathed in soft flowing fabric, these splits give the odd glimpse of a bare midriff, making the outfit very sensual.

Ao dai is made individually to fit each customer's shape to create the most graceful possible look. The pants should reach the soles of the feet and flow along the floor.

Comfortability is always taken into account for fashions and beauty. Tailoring must ensure the wearer's freedom of movements. Despite it is a long robe, ao dai must be cool to wear. Synthetic or silk fabrics are preferred as they do not crush and are quick drying, making the ao dai a practical uniform for daily wear.

The color is indicative of the wearer's age and status. Young girls wear pure white, fully-lined outfits symbolizing their purity. Older but unmarried girls move into soft pastel shades. Only married women wear ao dai in strong, rich colors, usually over white or black pants. However, ao dai is rarely seen in places where manual work is practiced. The nineties saw a real resurgence of ao dai. It has become standard and common attire for girl students as well as female staff at offices and hotels. Traditionally, ao dai has become the most preferred dress on formal occasions.

Early versions of the ao dai date back to 1744 when Lord Vu Vuong of the Nguyen Dynasty decreed both men and women should wear an ensemble of trousers and a gown that buttoned down the front. However, not until 1930 did ao dai appear partly similar to its look today. Vietnamese fashion designer-cum-tailor Cat Tuong, called as Monsieur Le Mur by the French at that time, lengthened the top so it reached the floor, fitted the bodice to the curves of the body, and moved the button line from the front to the left side of the body. Men wore it less, generally only on ceremonial occasions such as weddings or funerals. But it took another 20 years before the next major design change was incorporated and the modern ao dai emerged. During the 1950s two tailors in Saigon, Tran Kim of Thiet Lap shop and Dung of a tailoring shop of the same name, started producing ao dai with raglan sleeves. This creates a diagonal seam running from the collar to the underarm and this style is still preferred today.

Today, ao dai has been a bit modified. Its length is cut shorter usually just below the knee. Variations in the neck, between boat and mandarin style, are common and even adventurous alterations such as a low scooped neckline, puffed sleeves or off the shoulder designs are appearing as ladies experiment with fashion. Color patterns are no longer rigidly controlled and accesses to new fabrics have generated some dazzling results. However, most visitors to Vietnam have highly appreciated local tailors' skills when making ao dai. It is hard to think of a more elegant, demure and charming outfit, that suits Vietnamese women of different ages, than ao dai. Holidays or other Important Days

Vietnam celebrates many holidays, including traditional holidays which have been celebrated in Vietnam for thousands of years, along with modern holidays imported predominantly from western countries.

Among the traditional holidays, the two most important and widely celebrated are the Lunar new year (Tết), followed by the Mid-autumn lantern festival (Tết Trung Thu), although the latter has been losing ground in recent years.
