Taekwondo clothes are changed according to the martial arts of karate, and cardigan is changed into V-neck. Pure white is to reflect the spirit of soldiers' death, while Sanda clothes are more casual, usually brown and red loose vests, but they are rarely worn during training. Generally, they are shirtless and wear shorts, and their style is tough and rude. I don't want taekwondo to look so neat and straight.
