Why do some martial arts, particularly tkd, have studnts wear shirts with black collar, while their belt?

Question

is of other colours like white, yellow, green..

Answer 1

In my studios in America, only black belts got the black trimmed dobok. In my studio here in Korea (as well as another one I trained at here), the adults get black trimmed doboks and the children get red/black trimmed doboks, no matter their belt.

In fact, I just checked my black belt test photos, and ALL of the children and ALL of the adults (over 200 children, but only 14 adults) are wearing such doboks. I don't know if that's a KTF thing or just the association of the city I train in, but if ALL of the people from ALL of the studios in the city do something, I'm guessing it's a regulation from on high. Or at least a strong suggestion.

Answer 2

It varies a lot amng associtions. In some schools, the trim matches the belt. We wear white uniforms without trim. It just depends on what the Grandmaster wants.

Answer 3

My tkd class doesn't make us wear that! We have the black robes with a red color, with all the belt colors. We can wear anycolor shirt underneath the robes. I'm not really sure why your martial arts class does that.♥
