Brazilian Jiu Jitsu competitions now all have certain guidelines on how your BJJ Kimonos should be made and worn. Most Jiu Jitsu competitions follow the general rules for BJJ Kimonos given by the largest Jiu Jitsu federation known as International Brazilian Jiu Jitsu Federation (IBJJF).
The IBJJF has made these certain specifications about your BJJ Kimonos to make sure people don't alter their Gis to make it more difficult for their opponents to grab or use against them. These specifications are pretty simple to follow as most Jiu Jitsu Gi brands out there make their Gis competition approved.
The only colors allowed for your BJJ Kimonos would be the traditional white, blue and black. Combining any of these colors is also not allowed. For example,
if you were to wear a black Gi top with white Gi pants or white Gi top and blue Gi pants etc. this is not permissible. Both your Gi top and Gi pants should be the same color and generally the same brand and model of Gi. Your Jiu Jitsu Gis may not be too thick or hard to the point where your opponent will be obstruct and they must be made of cotton or similar material in good condition. Any Gis that have rips or tears in them anywhere will not be allowed for competition so again, make sure your Gis are in good condition.
The Gi top must be of sufficient length going down to the thighs and sleeves must reach the wrist when you extend your arms in front of the body. To make this is easier to understand just remember the longer the better and the shorter the worse it is.
If your Gi is too short for the wrist test or gi top skirt than they may not allow you to compete in that Bjj Gi but if it is to long they will still allow you. The reasoning behind this is to make sure your opponent has enough material on your Gi to grab.
As far as the Jiu Jitsu Belts, their widths should be about 4-5 CM and the correct color belt should be worn around the waist using a double knot, tight enough to secure the kimono closed. Proper hygiene is also a must for yourself and your BJJ Kimonos or else you will be disqualified.
In all, make sure you follow these simple steps provided for you to ensure your competition Gi will be legal for you to use. Shirts or Rash Guards are not permissible under your BJJ Kimonos as well during competition, although many smaller Jiu Jitsu tournaments may allow them on. Have a good time training, make sure your Jiu Jitsu Gis are competition approved with this article and good luck!
