This is the outfit worn by the World Martial Arts Human Champion in the age 1000.
It's the iconic outfit from the Martial Artist in the intro's tournament! His clothes were never used despite being all over DBO's promotional material. Since the unused armor textures in the game were either inaccurate or bad quality, I remade the textures from scratch to be of high quality. I've tailored a version for human girls too!
It's based off hsl_cos_501, aka the sub zero dogi(purple) , but it can be worn over any dogi model. My default recommendation is to overwrite the a_dogi_06 dff (The Dojo Dogi) in obj.pak/item/mesh_costume. The dds files only need to replace the files with the same name in tex.pak/item. Use DBOresourcetool to do so!
I might do the Namek Champion dogi at some point, but please don't give me requests or ask how to make your own mods. It's my first time modding.
