A Taekwondo uniform is called a dobok, which derives from the Korean words "do" (way) and "bok" (clothing) . The dobok is typically white, although it can come in many colors. The pants and sleeves of the dobok are wider and longer than the traditional Japanese keikogi. The dobok of World Taekwondo Federation-style practitioners usually have v-neck jackets, tailored after the design of the Korean hanbok. Traditional Taekwondo practitioners may wear dobok that are identical or very similar to keikogi, with a cross-over jacket front, while International Taekwon-Do Federation-style practitioners typically wear a newer design with a vertically closing jacket front. Around the dobok, a tti (belt) is worn, and the color of the belt denotes the rank or grade of the wearer. Colored belts are for geup-holders, while black belts are usually worn by dahn-holders. The order of belt colors may differ from school to school, but most commonly, the first belt is a white belt, and other colors are typically yellow, orange, green, blue, purple, red, brown, and then black. Some schools use other colors, such as brown in place of red and red in place of black. Some belts also have a stripe running down the length of the center of the tti, and a practitioners specific degree is often indicated with white stripes on their belt.
