The following are the dress requirements for Two Rivers Martial Arts students and instructors.

  1. Doboks: Students will wear a white dobok with the Two Rivers logo while training. Students will also have the option of wearing an Eric Heintz Black Belt Academy dobok or a plain white dobok with no logo. A complete uniform and belt are to be worn when training.
    1. When students begin training with Two Rivers, they may wear appropriate workout clothing, such as t-shirts and sweat pants (preferably without pockets). Once they are committed to staying at Two Rivers, they need to wear an appropriate uniform.
    2. When students transfer from another school, they may wear that school’s dobok for a reasonable time until they decide they will continue training with Two Rivers. Then they will need to wear a Two Rivers dobok, Eric Heintz dobok.
    3. Women and girls will wear a t-shirt, tank top, sports bra or other appropriate clothing under their dobok top. Preferably the garments will be white if visible. For first Dan and higher a black undergarment is acceptable.
    4. Men and boys will not wear t-shirts or other shirts under their dobok tops. Men may wear a plain white t-shirt with permission of their instructor.

    9. Doboks are to be clean and laundered with minimal wrinkles. Patches are to be securely attached.
    10. Colored or other special doboks may be worn according to the standards set for that group as approved by the Board of Directors. For example, a demonstration team might have its own dobok.
    11. Sweatbands, bandanas, hair ties, and hair clips are permitted as long as they do not detract from appearance.
    12. A white dobak, either with or without black trim, shall be worn for the Black Belt picture.
  2. Belts: Students will wear their belts with their uniforms in the dojang, at tests, and at demonstrations. Belts need not be worn for activities unrelated to training.

    2. Belts are to be tied in a square knot, and the ends need to be of equal length.
    3. For temporary black belts, the red is worn on top.

    5. Instructors eligible to wear an embroidered belt may wear a belt embroidered in Korean with red thread.
    6. Permanent first dan and higher black belts may at their option wear belts with their dan rank indicated by embroidered bars of the same color thread as the names.

  4. Jewelry: Students are not to wear jewelry when dressed in their doboks. Exceptions are made for medic alert bracelets, necklaces, or pendants and for wedding rings. Students choosing to wear their wedding rings are encouraged to wear only a wedding band because diamond rings can cut a fellow student when sparring. If a student wears a wedding ring with a diamond, the diamond should be covered with tape to lessen the chance of injury. Pierced earrings should be removed if possible.
  5. Shoes: Students are to train barefoot or in martial arts shoes. The martial arts shoes are to only be worn in the dojang.

    2. Hats are not to be worn in the dojang.
    3. Visitors, parents, and others entering the dojang will remove their shoes and hats to enter the dojang.

Students unwilling or unable to comply will be asked to change into their street clothes and may watch class from the audience or leave.
