A standard karate Gi (the white clothes that look like pyjamas)
The Karate costume/uniform is called "Gi".
There are a number of stores that stock Karate Gi's. Stores such as Pirana Gear, Asian World of Martian Arts and Boxing Supplies all stock Karate Gi's.
Karate is practiced in bare feet. The karate uniform is called a gi.
"DOGI" Gi for short.
In my Karate school the American flag goes on our right shoulder.
o robe or a gi
The uniform worn when practicing karate is called a gi. There are similar uniforms in other types of martial arts.
Generally not unless it's at the beginning of a sentence. First of all in actual Japanese it would be called keikogi, dogi or karategi not just gi. Second in actual Japanese there are no such things as capitals. Third in English usage gi does not fall in to any of the capitalization categories (proper name etc.)
Depends on the martial art. Karate has a Gi. Taekwondo has a dobock.
Helmet, gloves, mouth guard, a gi of course, etc...
If you mean putting badges and logos you just buy them and sew them on
