Traditional Vietnamese dress is known as the ao dai, a long tunic worn over loose-fitting trousers. The ao dai is typically made from silk or cotton and features a high neckline and side slits, allowing for ease of movement. It is often adorned with intricate patterns and vibrant colors, reflecting the wearer's personality and regional culture. The ao dai is commonly worn during special occasions, such as weddings and festivals, and is a symbol of Vietnamese heritage. Both men and women can wear variations of the ao dai, with styles differing slightly to suit each gender while maintaining the garment's elegant silhouette.
