What do you have in mind for the style and theme of the t-shirt?
Cartoonish Brazilian Jiu-Jitsu Kids themed shirts, with the same design but differences in the belt color based on the kids level. I'm open to designs such a cute bear cub, lion/tiger kitten, standing with their arms crossed or hands on their waist while wearing a Brazilian Jiu-Jitsu Gi and their belt displayed. My logo should be a small patch on their gi, noticeable but not dominating. The Gi can be white, blue, or black, and one pink option for female children. Another option would be to have all the belt levels represented with several characters standing in a v-shaped formation and the lead which should be a green belt holding out a gold medal and the other belt levels behind in V shaped with their arms folded looking tough.
my logo appearing to be a patch on the gi, the gis must be either Blue, White, Black. with the exception of a pink gi for females and must have Brazilian jiu-jitsu kids belt levels
