I was not sure but I think the white karate uniform is a cross over and not the pull over like the other TKD gi's. I had to ask my instructor and he said that was correct. I am just starting karate training. I had experience in some other Chinese arts but never Japanese styles before. So the whole uniform thing is new to me. After class he gave me a site that I can go to to get one http://www.tigerstrike.com/our-gear/karate-uniform-white/ and said it would not be too expensive.
I love this particular blog about karate: http://www.24fightingchickens.com it is humorous but informative if you have a few minutes to read it.
Here you can see all the different names for the parts of the uniform. It is very interesting as the Chinese outfit does not have all those different pieces.
This is Rashad Evans explaining boxing. The traditional kind versus using it in MMA.
So stay light on the feet and move around while throwing jabs to the face and body. Then when the opponent has had their brains scrammbled then you can lean in and throw som heavy blows.
