Simple concept, a Gi, with both male and female versions, maybe coming in diffrent colors, has a unique symbol on the back, that takes up all clothing slots and can be activated to deactivate all buffs on self with a visual effect to let people know.
Why?
Well the only way you can really trust someone in a tournament is if they dont wear any clothing what so ever. This can really subtract from the whole experience as if you allow clothing those less then honorable will cheat and wear clothing that gives them an edge.
A Gi that can be identified (with the aforementioned symbol) that blocks the other clothing slot and deactivates buffs with a vissual confirmation would be a perfect thing for tournaments as it will allow some class and force honesty in them.
