Veja uma tradução

Hanbok is the name of the two piece clothing that is worn by women and men. Women have a long sleeve top and a floor length skirt that starts under the arms. Men wear a long sleeve hip length top and loose fitting pants. Traditional clothing worn by Koreans during important holidays and life events. It is talking about traditional clothing versus western style clothing. Vietnamese also have lovely traditional clothing that encompasses long pants under a lovely floor length tunic. I have seen this type of clothing during Tet. I hope that this helps you to understand what traditional clothing means.
