What are the Gi uniform requirements?

Our uniform policy is as follows for Gi divisions:

Competitors can wear a Gi of any colour as long as it is not overly long or short. Referees reserve the right to ask a competitor to change their Gi.

Competitors must ensure their belt is not overly short and remains grippable for an opponent.

Competitors may wear patches on their Gi as long as they do not prevent grips.

Competitors may wear a rash guard under their Gi.
