Hanbok was worn daily up until just 100 years ago, it was originally designed to facilitate ease of movement. But now, it is only worn on festive occasions or special anniversaries. It is a formal dress and most Koreans keep a hanbok for special times in their life such as wedding, Chuseok (Korean Thanksgiving), and Seollnal (Korean New Year's), Children wear hanbok to celebrate their first birthday (Hangul: 돌잔치) etc. While the traditional hanbok was beautiful in its own right, the design has changed slowly over the generations. The core of hanbok is its graceful shape and vibrant colors, it is hard to think of hanbok as everyday wear but it is slowly being revolutionized through the changing of fabrics, colors and features, reflecting the desire of people.
