On the evening of April 9, the show "Our Ao dai" took place in Hanoi. The event is part of the Vietnamese Heritage Ao dai campaign of the Vietnam Women's Union. The show was held to promote the beauty of traditional Ao dai in modern-day. This year, the show is organized by Thang Long Research Institute and Elite Dat Viet magazine. With the main theme "World in Vietnamese Ao dai", the show introduced 15 collections of Ao dai designed by 15 Vietnamese designers. More than 600 unique designs were shown, bearing the colors of 15 different cultures around the world. All collections in the show were inspired by colors and architectural works that represent each country. These Ao dai were made by using traditional Vietnamese materials, such as silk and hemp./.
