A martial arts uniform, often called a gi or dobok, is a specialized outfit worn by practitioners during training and competitions. These uniforms are typically made from durable cotton or polyester fabric to withstand rigorous movements. The design usually includes a jacket, pants, and a belt that signifies the practitioner's rank. The color of the uniform can vary depending on the martial art style. For example, karate uniforms are usually white, while taekwondo uniforms may be white or black. The belt system, which ranges from white to black, represents the student's progress and skill level in their martial arts journey.
